Answer 1

If you are using a different user for a reason, e.g. when having httpd-itk (RHEL/CentOS/Fedora) or apache2-mpm-itk (Debian/Ubuntu) and your main user is not apache or www-data, then do:

sudo usermod -a -G apache youruser

or

sudo usermod -a -G www-data youruser

depending on your distribution, then phpMyAdmin will work.

Answer 2

I encountered this after a parse error in config.inc.php. Unfortunately, phpMyAdmin sets error_reporting(0) while reading the configuration file. Open libraries/Config.class.php, search for $old_error_reporting = error_reporting(0); and replace it with $old_error_reporting = error_reporting(E_ALL); to see what's going on. Of course you should revert this change later for security reasons.

Answer 3

Pretty much as other users had said... I'm running Debian 8 with PHP7 and ran into the issue, so just installing;

sudo apt-get install php7.0-mbstring

Followed by restarting the Apache service;

sudo service apache2 restart

And then phpmyadmin ran fine.

Answer 4

For Debian users: (I ended up in this thread as a Debian user) I read @naveen 's answer and it appeared I didn't have php-mbstring installed, installing it solved my problem:

sudo apt-get install php-mbstring

(After installing php-mbstring, don't forget to restart Apache:)

sudo systemctl restart apache2

Answer 5

For me the error was in /usr/share/phpMyAdmin/libraries/sanitizing.lib.php.

I increased php error reporting following this advice and commented the offending line in sanitizing.lib.php by prepending // in front.

Then the error was more descriptive: Fatal error: require_once(): Failed opening required '/usr/share/php/php-gettext/gettext.inc' (include_path='.') in /usr/share/phpmyadmin/libraries/common.inc.php on line 477

I noticed that I somehow lost the php-gettext debian package, but after installing it phpMyAdmin worked again.

Answer 6

Check that your session directory is writable by the webserver process.

The best way to do so is to create your own phpinfo file; in any web accessible folder create a file (you can call it test.php or phpinfo.php or whatever you'd like) with the following content:

<?php
phpinfo();
?>

Open that file in your browser (http://localhost/test.php or similar) and look for the line session.save_path. That's your session folder; make sure the permissions are suitable and see if that helps.
