wp-admin shows blank page, how to fix it? - php

Question

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.

Answer 1

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.

Answer 3

Go to your functions.php page and delete any spaces immediately above or below your PHP tags.

Answer 4

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.
I also had a blank screen for my blog.

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!.

Answer 8

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.

Answer 9

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 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.

Answer 16

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.

Answer 17

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.

Replace it with the statement: <?php echo $this->_help_sidebar; ?>

Answer 21

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.

Answer 22

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.

Answer 23

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.
