Warning: require(/home/militia/public_html/sources/ipsclass.php) [function.require (http://www.the-militia.biz/forum/function.require)]: failed to open stream: No such file or directory in /home/militia/public_html/forum/index.php on line 61

What does that error mean? How can I fix it? I am not going to pay for "official support" on IPB's site when I ask other places for free.

Anyone know?

Thanks
