Downloaded the latest phpMyAdmin to be used on macOS 10.15 Catalina (local webserver), extracted the phpMyAdmin files to my web root.
During the setup I chose config authentication and now when I visit the setup page I'm getting some mysqli error.
I deleted the entire phpMyAdmin/ dir and wanted to start all over again. However to my surprise, the previously entered (incorrect) server details are still there.
I would assume the any config.inc.php would be saved within phpMyAdmin's own dir, but apparently it's saving this data somewhere else.
How/where can I find it, so I can delete it and truly start a complete new phpMyAdmin setup from scratch?
P.S. I already tried:
/etc/phpmyadmin/
/usr/local/phpmyadmin/
/usr/local/etc/phpmyadmin/
/usr/local/opt/phpmyadmin/
But neither of these dirs exist.
If you've simply downloaded the phpMyAdmin file yourself and uncompressed it to your web root, then the config.inc.php file goes in that phpMyAdmin folder. If you've used brew or some other package manager, they each have their own location for configuration files, but that doesn't seem to be the case here.
It's not clear why the old server details have been retained, maybe your browser has cached the old page or something, but the only place that phpMyAdmin looks for the configuration is in the main folder. Is there a chance you're seeing the defaults, rather than some custom setting? (The defaults would be to use auth_type cookie connecting to host 'localhost').
What is the specific mysqli error message you're seeing?
I am using Ubuntu 12.04 Operating System. I have suddenly encountered a very strange problem. My "PhpMyAdmin" interface is not opening in "Mozilla". But it is opening in another browser named as "Chromium".
Problem:
When i try to open it from Mozilla, it shows me the following error:
But in other browser "Chromium" it is working totally fine.
I searched about it on the internet. Everybody says it is a permission issue on the "config.inc.php" file. I have tried many solutions provided on the internet, but none of them worked.
Question:
My question is that if it is indeed a permission problem then why it is working in the "Chromium" browser but not in the "Mozilla" browser..
It looks like you are logged in one browser and not logged in another. That forces different routing and, therefore, in one case the permission on config.inc.php is being checked and in other case—not. Nevertheless you should fix the problem with executing
$ chmod a-w config.inc.php
from the directory it belongs to.
If you're using an interpreter, try to set Mozilla as your default web brower in the settings of your interpreter.
it's so annoying.
I'm working with Netbeans and Chrome (but other browers are not better) and i never know whether an error comes from last edited code or previosly edited.
app_dev.php suppose to take care of that, but its not.
I do not know whose cache is responsible for this: Netbeans, Symfony, Browsers.
How to contrain displaying latest version of my code?
edit
if do following steps its not work well:
physically delete cache (even command cache:clear --env=dev)
change code
refresh site
if do following steps its work well:
change code
physically delete cache (dev)
refresh site
Netbeans is an IDE. It will not cache any files I think. Try following this steps:
Use Ctrl+F5 in Chrome to refresh the page with discarding the browser cache
Execute php app/console cache:clear --env=dev after each source code modification
Check your URL in browser address. It should be something like http://localhost/web/app_dev.php
#Olim pretty much covered it all. Only thing I would add is to try physically removing cache directory and running cache:clear again...
EDIT:
I had numerous problems with access rights of my IDE (phpStorm in my case) which could not alter files stored in Apache's default location (C:\Program Files\Apache...). The main cause was the dreaded Windows's UAC which prevented any program to write in some more sensitive locations.
To solve this you can either disable UAC or you could set the proper ownership:
Right click on you project's directory
Click Properties
Click the Security tab, then Advanced button
Switch to Owner tab and then Edit button
Click Other users and groups and enter your username. Click OK
Make sure you check the Replace owner on ....
Restart all related software (Netbeans, Chrome, Apache service...)
Does it work now?
I have a weird problem I cannot seem to solve (as a php noob).
I am working on simple php site (no sql involved). Everything was working perfectly till the moment I decided to copy over the files and edit them on another computer. All worked fine on the other computer as well. Then I took the files and copied them to the first computer again. Here came the problem: if I try to open ANY file copied from the second computer, it doesn't show anything, just a blank page. Even if the file was not edited at all on the second computer.
For example my index.php:
1. Copied from comp 1 to comp 2, no edits done
2. Copied from comp 2 to comp 1
3. Opened in the browser -> blank page
What's going on here and how to solve it? Is it some cache that apache is keeping? How to clear it? Both computers with OSX, however the second one was running MAMP, while the first had php/apache/sql set up.
Your permissions need to be set up correctly. Do the following:
Change the owner of the group to your user
chmod 0755 all the directories
chmod 0644 all the files
Then you are good to go!
You need to make sure that your permissions are set up correctly.
Apache Permissions
The blank page is displaying because Apache is encountering a PHP error somewhere, but is not set to display PHP errors.
Check out what is going on in your Apache error log and work from there. You could also look in the Developer Tools of a browser like Chrome, or use Firebug, to see what response your browser is getting from the server (most likely a HTTP 500 error).
I wouldn't recommend blindly changing ownership on files and directories until you know what is going on.
I have phpMyAdmin on a remote server. It was fine until today, I used it many times (so the username and password are fine). However, today the whole site did not worked, it simply said "too many connections".
First I retried to restart Apache and MySQL, and it didn't fixed the problem.
Then I rebooted it with shutdown -r now, and the main site does work now, but phpMyAdmin still won't log in (and it does not show any error). After typing my user and password and hitting enter, it shows the exact page (with no error) as nothing would have happened. I can see that the token is different in the Address bar though.
I tried removing all php sessions manually from /tmp folder (by ftp), and it has the same problem. Could the database of phpMyAdmin itself be corrupt? How can I fix this?
Thanks in advance
My issue was, I was using HTTP instead of HTTPS. I don't know why, my server allows both connections, but I must have made a change some where so it only allows HTTPS connections. Once I switched over, the website started to work again.
In my case, the hard drive on the server was full.
In Linux, use df -h to view the available space on the hard drive and clean up unnecessary files.
I just spend forever troubleshooting this.
You are missing the mcrypt extension.
The mcrypt extension is missing. Please check your PHP configuration
You can check if this is the case by forcing
$cfg['Servers'][$i]['auth_type'] = 'http';
and looking at errors when you login.
Possibly no space left on the device. In many cases it will not allow to create the session due to lack of space for the file.
Possible reasons are-
a) user has been locked.
b) There are too many users more than specified.
c) Your System/Ip (rights were provided to which) has been changed.
Please follow below steps-
Step1: Please server connect with root user and check if you are able to use your DB.
Step2: execute below commands.
mysql> flush hosts;
Now try to connect from phpmyadmin if success then fine other wise check if you are getting any IP related error if yes then check if that ip have required permissions.
Other Reasons may be
opened_files_limit crossed whatever you mentioned in your configuration file.
disk full.
too many thread opened/too many connections.
your login_user has been locked due to wrong password input a certain times (limit mentioned in configuration file default is 10).
mysql port (default is 3306) is not open on DB server from outside.
user does not have permissions from your system IP. etc.
In my case, it was that I was trying to access through HTTP, not HTTPS.
Once I changed the address to https://mysite/phpmyadmin I was able to access.
I had similar problems with login. I solved it by clearing browsing data in Chrome. Maybe just simple restarting Chrome would be enough. I noticed that I was able to login in incognito mode even without clearing browsing data or restarting Chrome.
Interesting when I was trying clearing cookies for site manually it didn't solve the problem.
Check if there is enough space available on server. In my case it was space problem. I deleted some files and its working fine now.
To check available space : df -h
To check available inodes : df -i
CodeIgniter cache was taking so much space.
If there are multiple MYSQL connection running simultaneously, PHPMYADMIN won't allow you to login (neither it'll show any error).
Either you need to increase your max_user_connection value (you can do that via ini) or you need to wait for sometime and try.
Had the same issue.
I made a typo in my php.ini file (letter 'B' at the end of 2GB is the error):
post_max_size = 2GB
upload_max_filesize = 2GB
Apache started up but the php.ini file didn't load correctly. After fixing the typos and reloading Apache every thing worked ok.
Another reason not mentioned so far:
Modifying the webserver headers such as X-Frame-Options and others can have an effect on loading any page post-login. After login, you may see the login page refresh, but notice the address bar shows index.php+hash (meaning you are actually logged in). Or, you may simply get a blank page.
Use a browser inspector to check your PMA login page for headers received - if you see something, check your webserver configuration files for header modifications. In my case X-Frame-Options was set along with others. Once I commented these out, PMA was fine..
sudo htpasswd /etc/phpmyadmin/htpasswd.setup admin
a redirect can cause error.
for example this lines in .htaccess in root folder :
# redirect all index.php to the folder root
RewriteCond %{THE_REQUEST} ^.*/index\.php
RewriteRule ^(.*)index.php$ /$1 [R=301,L]
to solve it , you can simply create a .htaccess in PMA directory and put this line in it :
RewriteEngine Off
My issue was a hard coded host ip in the config file:
$cfg['Servers'][$i]['host']
Since my host IP has changed, I started having the issue.
Hope this helps someone else.
This is just a work around but it works for me. When trying to connect to phpMyAdmin use the local host IP address instead of the word 'localhost'.
For example type '127.0.0.1/phpMyAdmin'
