Thread:Project:Support desk/Special Pages is Blank and PHP error log blames skin template

Mediawiki version 1.24 PHP 5.4 mysql 5.6.22

My special pages is blank (no header etc)

The error log outputs one of two different lines

[14-Jan-2015 11:37:55 UTC] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 49152 bytes) in /home/XXXXX/public_html/includes/skins/SkinTemplate.php on line 1347 [14-Jan-2015 11:48:02 UTC] PHP Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 12288 bytes) in /home/XXXXXXXX/public_html/includes/skins/SkinTemplate.php on line 1587
