I've got a major issue with PHPMyAdmin since a recent update. If I try to access any PHP files in the phpmyadmin (/usr/share/phpmyadmin) directory I get a 500 error. This even happens if I simply create a
<?php
phpinfo();
?>
file to display current PHP info in the same directory.
I don't have this issue in other directories on my server. MySQL is working fine, and I can create and modify tables manually. WordPress sites on my server relying on MySQL work fine.
I did notice I was getting
Allowed memory size of 262144 bytes exhausted (tried to allocate 7040 bytes) in /usr/share/phpmyadmin/index.php on line 141
However, this doesn't happen constantly and the 500 error happens regardless. I've checked the php.ini files for all types (CGI, CLI, apache2) and all have a 256MB memory limit which seems ample. I tried increasing it to 512MB and restarting apache2 but to no avail.
This only seems to have happened since a recent update about 2 months ago.
Any ideas what might be causing this? Other software on my server such as roundcube webmail, WordPress and others work absolutely fine and do not present errors.
Thanks in advance for any help.
UPDATE As a workaround I've installed a seperate copy of PHPMyAdmin in a different area (without touching the Debian installed version). This works fine so I'm cosidering it a workaround for now. There must be some sort of PHP configuration issue that is denying access to the directory or not allocating any memory at all for one reason or another. Solution not yet determined.
