Zadax you have edited the forums code, unless you can find someone to go through your changed code for you line by line and workout where you have messed up then I'm afraid you are on your own with this one.
You will just have to keep going through all the code you have changed and edited and workout what is coursing your problem, also if you have any mods this may also course this.
As you forum is havily modified and not a standard fresh install it's almost impossible to workout what would be wrong as we don't know what you have changed.
