Yeah, I don't know why he did that, but one of the times he did it, it was for my site and it worked like a charm

Your ultimatebb.php should be chmod 644, use the chmod +x to give it execute access, otherwise it won't work. I can update it for you if you'd like... It's just what I've had to do on certain boards.

well.. with chmod 777 permissions.. it HAS everything - including execute (the 7 marks execute rights). so already - the php file has execute permissions...

so if like you say - the file should have 644 - then effectively - there are no execute rights on the owner, group or the world...

744 - owner has execute rights.. - world and group - has r/w

so my original permissions for the file was to have everyon - world, owner and groups - to have execute - and this made the effect chmod to 755 - which is what i've had all along.
