Chmod 777 is disabled - how to enable

[khorinis]

Hello,
i try to run a script with chmod 777 and i get a "500 Internal Server Error".
Which option could blockate that?

I tried already "/scripts/fixeverything"-script from cpanel and insecure file permission but it doesn't help all. (Does it could have set something back?)

It's for woltlab burning board 3 because it won't work with chmod 777 (just temporary).

Just guessing but it sounds like your server may have SuPHP enabled, if yes, you should make sure the directory your script is in has perms of 755, files in it, 644.
