I would like to change the theme file through the Wordpress Admin Panel, in menu Appearance > Theme Editor, but I've got the message:
Something went wrong. Your change may not have been saved. Please try again. There is also a chance that you may need to manually fix and upload the file over FTP.
Everything was working correctly before I've made some changes in the file and upload it through the FTP back to the server. I am able to change every other file in Theme Editor, but this one. The rights are the same as in other files I am able to change, the owner and group are the same too. It looks that everything should work, but this and only this one file I have updated via FTP I am not able to change through the Theme Editor of Wordpress Admin Panel.
Any idea what could be possibly wrong? What I have done wrong? Please help me somebody, in the most of the time I am on the "safe" network, and the server FTP is not accessible from my computer.
Thank you.
Check Theme Permission
One of the first things you got to check the theme files and folder permissions.
If you are running on shared hosting then mostly it would be alright. However, if using VPS or Cloud then you got to ensure the same user owns theme files as web server (Nginx or Apache HTTP) running.
Modify File Permissions with chmod
FYR :- https://www.linode.com/docs/tools-reference/tools/modify-file-permissions-with-chmod/
Check Security Plugins
Are you using any security plugins? Do you have the option to check their logs to see how exactly your request is being treated?
Alternatively, you can quickly disable the security plugin and verify if that works.
I have finally solved the problem. There were two things with I have mislead my question.
The first one was that I wrote "Everything was working correctly before I've made some changes in the file and upload it through the FTP" and after that I wrote it again in the comment of the answer - I was so sure that I have tried the same file before, but I have not, it definitely was another one, I am sorry.
And the second was that I did not write specific file name. The file was includes/_wp_utils.php. Somebody would maybe notice that this is the biggest file in that directory. And that was the problem. I do not know why - maybe it was too big for server processing or something else (120KB), but I noticed it later, and I have tried to split the file to a few smaller files and I have included them into the includes/_wp_utils.php with the command include_once __DIR__ . '/_wp_utils/_nth_part_of_original_wp_utils.php';.
Thank you #G.D Udara Lahiru Sampath, I absolutely liked your answer. It was useful and very important to check.
Running an instance of Bitnami Wordpress on AWS Lightsail. Getting the following screen when trying to activate a Wordpress theme (JobCareer):
UPDATE #1 Turned on debug and saw the error information in the above screenshot.
Other themes and plugins I have tested all installed and activate without issue, so it's probably something specific to this theme.
I have made sure that define('FS_METHOD','direct'); is set inside wp-config.php file.
The wp-content folder and sub-folders/files are all chown to bitnami user and have the appropriate permissions (folder:755 & files:644).
At a loss as to what else to try. Thanks for any help you can provide! :)
It's definitely a files & directories permission issue. Move the define('FS_METHOD','direct'); line back to where it was (that change is causing a different error).
The 'www-data' user is the default user for Apache (and other HTTP servers?), in case you didn't know.
Here is my official WordPress forum support plea: http://wordpress.org/support/topic/headerphp-is-not-updating?replies=4
I changed all the permissions via FTP, currently set to 777. Originally 666, but that didn't work, so here we are.
I cleared all of my browser caches.
I added the following line to wp-config.php:
define('DISABLE_CACHE', true);
I don't know what else to do at this point. The file on my server reflects the changes I made, but if you look at the source on the website, via Firebug or whatever, it isn't there.
From the native WordPress editor, it says I can't edit the file because the permissions aren't set. What's really absurd is that this is a custom theme specifically for this website. Whose business is it if I want to change it?
Can anyone please at least verify that the correct 'header.php' is in wp-content/themes/themeofchoice?
EDIT: I don't know what happened but suddenly my changes have taken effect. I guess Wordpress takes hours to update .php files? WOW.
Thank you for your answers everybody. If anyone has similar problems, I guess take the same steps I did. If anything changed, I continued to change the permissions of all the parent folders as was suggested.
I am working with WordPress 3.5.8. Yesterday I made some changes into it to a friend. I don't know what happened, but after some time when I try to log in at wp-admin side and execute URL www.mysite.com/wp-admin it shows me a blank page. How do I solve this? I have searched over the internet and blogs. I found it could be related to hosting problems or brute force-attack, but I don't think that that's what happened to my site.

After dozens of times trying to fix this problem reading forums and posts, reinstalling WordPress, removing white spaces, putting lines of code in wp-config.php, index.php, admin.php, I fixed the issue just by renaming the plugins folder to "pluginss" in FTP. So wordpress asked me to update the database. I updated and I could enter at /wp-admin. A plugin was causing some conflict, so when I rename the plugins folder, all plugins automatically has been disabled.
As I was inside the /wp-admin dashboard, I could rename the "pluginss" folder to the regular name and start to activate all the plugins one by one and see what plugin was broken.
Now is 100% fine.
Try turning on WP Debug. If this is happening due to a PHP error (which I bet that it is), you will be able to see what's going on and fix the error.
Go to your functions.php page and delete any spaces immediately above or below your PHP tags.
I faced the same problem and I tried many things such as trying to login through wp-login.php instead of /wp-admin and adding ob_start() in /wp-admin/index.php (if you hit the url /wp-admin it goes for /wp-admin). It showed login page but entering the username and password shows an error like "cookies are blocked due to unexpected output".
I finally got the solution: it happens because the theme or plugins that you installed are not supported.
How to check and fix:
Rename the plugin folder name and theme folder name. If opening /wp-admin and entering a valid username and password the dashboard is shown, then it worked.
Revert the folder name of plugin and theme, then activate the themes and plugins one by one, cross-checking with /wp-admin. You will find out the unsupported plugin or theme.
I also had a blank screen for my blog. The solution was to copy up a backup copy of wp-config,php somehow the 'live' wp-config.php had been replaced with a file size of zero.
In my case I had the same problem. Helped remove the wp-config.php file.
Wordpress created new wp-config.php file and wp-admin is working flawlessly now.
Rename plugins, themes folder does not help.
[6] was spot on. I had the same problem
ie a blank screen where wp-admin should have been
Renaming plugins to pluginss let me get back in.

It seems that it is very important to have an off-line backup
The easy way to copy of the files is Filezilla (freeware)
You need a wordpress plugin for database backup - ie to back up all your pages and posts.
But the pros will tell you that you need to get a

All your problem is solved right now just follow this instruction:
go to your themes then de activate your current theme, just put "x" in the the first letter of your theme name.
for example this is your theme folder name: "mytheme" just put "x" in the first letter like this "xmytheme" tho di activate.
Then after that go back to your wp-admin panel then BOOM! wp-admin accessable.
When you access your wp-admin panel or you are on your dashboard, again activate your theme again, but before that. REMOVE THE "X" letter you putted in your theme name.
example: "xmytheme" just remove "x", output like this: "mytheme"
then activate it in your dashboard.
hope this help!.
In my case, I was able to see the backend, but in my front I was getting a blank page...
Nothing about debugging and disabling themes/plugins was useful...
After some research, I've realized that my index.php (located at the root directory, not the theme's one) was empty!
The only content was a message saying Silence is golden.
Using a backup I had, I could get back my original index.php and get the site working again.
It might be because of a few reasons:
Problems in your web host.
Theme related errors(You can change it by renaming theme folder).
Plugin related errors(You can change it by renaming plugin folder).
An Empty line in your wp-config file.
Code errors that can be seen by enabling Debug mode.
"define('WP_DEBUG', true);
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
#ini_set( 'display_errors', 0 );"
Remove blank space in functions.php or you can also remove the last "?>"
I ran into the same problem a few minutes ago, the problem was when I uploaded my local theme I had a bunch of tags separating each function I had in there I solved this by putting all the functions in one php tag... Hope this helps.
I had this problem (not showing /wp-admin/), when I moved my site to new host. i solve this problem by:
1. Re mane activated theme's folder
2. Install that them again and active it
3. copy and re place some customized file like .css .js from backup
Now problem solved.
I just had this and it was a file / directory ownership issue.
Fixed via SSH and changing the ownership recursively (-R):
chown -R ownerID:groupID /home/mydirectory/website
Change ownerID, groupID and filepath to be relevant to your own situation.
Just reset the password, this will work.
I was also facing same problem but i renamed contact-form-7 plugin from /wp-content/plugins directory to contact-form-7-rename and problem solved.
So this is due to unsupportable plugins or theme.
That white screen of death happened to my blog, and what I did was that I renamed the theme and plugin, and everything was back to normal.
In my case, wp-admin/post.php blank screen was fixed by removing the " ?> " at the end of my function.php in my child theme. I don't know how the end tag ended in there, but removing it solved my problems.
Just visit the plugins folder and delete the last plugin you uploaded and should do the trick.
I found following solution working as I was using older version of wordpress.
Open file blog/wp-admin/includes/screen.php in your favorite text
editor.
on line 706 find the following PHP statement: <?php echo self::$this->_help_sidebar; ?>
Replace it with the statement: <?php echo $this->_help_sidebar; ?>
Save your changes.
i have wasted a lot of time to solve it , But the only solution i find is to rename your word press plugins folder and active theme , and your wp-admin will be visible , so then you can change and check for suspected plugin or theme.
first of all check your internet its connect!
second is turn on WP_DEBUG and write this codes in wp-config.php
define('WP_DEBUG',true);
error_reporting('E_ALL');
ini_set('display_errors',1);
third is rename themes and plugins folder that in wp-content folder to other name sush as
pluginss , themess
S F my english!
Had this same issue after changing the PHP version from 5.6 to 7.3 (eaphp73). So what I did was I simply changed the version to alt-php74.
So what's the problem? Probably a plugin that relied on a certain PHP extension that wasn't available on eaphp73.
Before you touch any wordpress files, just try changing your site's PHP version. You can do this in the cPanel.
And if that doesn't work, go back into the cPanel and activate every PHP extension there is. And if your site starts working at this stage, then it's probably an extension it couldn't function without. Now slowly work backwards deactivating (one at a time) ONLY the extensions you just activated.
You should be able to figure out which extension was the required feature.
Can it be a plugin that's causing the issue? Certainly. Maybe the rogue plugin just wanted that extra extension.
If changing the PHP version, and juggling with the PHP extensions didn't work, then try renaming (which automatically deactivates) one plugin folder at a time.
I have experienced the same problem as well. The reason was, that the functions.php was configured wrongly.
I did the following to solve the problem:
In my child theme, I backed up all my files
Then I deleted all of them leaving only the style.css page.
I could then log in.
On reloading my functions.php I found it was the culprit. I rewrote the php and it was fine.
My case was that I had generated code for three custom content types and then just pasted all the code in functions.php without renaming the "function custom_post_type" part of each function. After renaming like e.g "function employees", it worked like a charm....it displayed.
