Not able to post replies in these forums
It seem like the tw.o forums suffer from this bug.
I'd like to post a reply, but I can't because every time I get this error message about $thread_sort_method being empty. The "go back" button on the error doesn't work either as it leads to another error "No thread indicated". So in the end I lose my already typed reply text and am kicked back to the homepage, making the forum basically unusable.
In a local installation I had the same problem, and editing the comments.tpl file (like written in the comments of above bug report) is an acceptable workaround.
Happens to me in firefox both on linux and windows. Oh, and it looks like only non-admin users are affected.
