Thread:Project:Support desk/Special:SpecialPages returns a 500 server error/reply (3)

Okay, that helps...

Going to Special:SpecialPages returns:

Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 4864 bytes) in /var/www/vhosts/actioncoachtest.com/httpdocs/mediawikitest/includes/specials/SpecialVersion.php on line 44

When I try Special:Upload I get something similar:

Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 19456 bytes) in /var/www/vhosts/actioncoachtest.com/httpdocs/mediawikitest/includes/api/ApiQueryInfo.php on line 440

So it sounds like 16MB isn't enough to even get started. Is this a php function? Being rather new to this, where would I look, or what would I have to ask my network provider to do for me?
