Thread:Project:Support desk/Special:SpecialPages returns a 500 server error/reply (5)

16MB is most definitly not enough. 32 MB would probably just barely work, but I would reccomend increasing it to at least 64 MB.

To increase the memory limit, you have to edit your php.ini file (look for the memory_limit directive). On unix systems this file is usually in somewhere like /etc/php/apache2/php.ini (or something like that). If you're on a shared host you may have to talk to your hosting provider.

(For more info on php.ini see http://php.net/manual/en/configuration.file.php )
