"How did you get to this topic, then?", you may ask.General Error
Language file shout.php couldn't be opened.
Well I opened the main page in an other browser without logging in, and copied the link of the forum categories, viewforum.php?f=103, for example.
The JavaScript is also broken, on the main page I even got a "recursion too deep" error. I looked into the source, and i found that the function that would display an error message generates an error.
Also, at the end of styles/Infinity/template/editor.js there is a misplaced catch.
