Are you sure your PHP version is below 4.1.0?  Because... the minimum requirement is PHP 4.1.0....

I receive the "invalid referring site" error when I try to delete a topic on one of my forums.

This error is generally caused by using redirection and/or frames.

nuts.

Will SMF be equally unhappy with frames?

[DeN-U-BiS]

ok i am doing neither
my address is the raw address from the host i am with
so its not on a domain or anything
i am not using a redirector either <ie: noip.com>

and i am not using frames
<didnt do any styles or anything to my yabb....in other words its ugly looking LOL!>

SMF shouldn't have these problems as bad.

The reason it's having problems is usually because the referrer is not the forum, which is a HUGE security risk.  Turn the check off and I can hack your forum no time flat.
