I am having a problem with the post.php file, which is annoying me a lot. It doesn't affect me though, only other people who visit my site which is very odd. Whenever somebody else views post.php, they get this error:
Fatal error: Cannot redeclare check_cookie() (previously declared in /vetinari/sinkhead/public_html/forum/include/functions.php:2) in /vetinari/sinkhead/public_html/forum/include/functions.php on line 2
I tried tinkering with it a little, but I'm not too good at PHP so I restored it back to the original after a while. So now I'm stuck. Please can someody help me get round this troublesome problem? I've tried telling them to clear their cookies, in case that was the problem, but that doesn't fix it. Please help!
EDIT: If anybody wants to try it, the URL is http://sinkhead.net/forum and the username and password are both demo.
