Problems with the ZC Wiki

Okay, I am experiencing some serious technical issues with the ZC Wiki.

1. When I try to log out, it gives this error:
Parse error: syntax error, unexpected T_STRING in /home/evouga/shardstorm.dreamhosters.com/wiki/includes/specials/SpecialUserlogout.php on line 34

2. When I try to edit any article, I get these errors:
Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home/evouga/shardstorm.dreamhosters.com/wiki/includes/PatrolLog.php on line 89
Parse error: syntax error, unexpected T_STRING in /home/evouga/shardstorm.dreamhosters.com/wiki/includes/PatrolLog.php on line 89
