Don't have access to index.php error.

[WaddleJrJr]

Sometimes when users try to create a thread on my forum, a xenforo overlay will show up that says,
"The following error occurred:
Forbidden

You don't have permission to access /index.php on this server."

I checked, and permissions for index.php are the standard 644. This error seems to happen at random, but when it does happen it lingers around for quite a while, and retries and refreshes don't seem to fix it consistently.

Maybe I should write a guide on configuring it for XenForo?

What rules need fixing for this issue ?

Do all the problems go away if you turn off mod_security ?

Yup, turning off mod_security solved the problems.

Yes !
Include some information about how to Whitelist things.

How did you do this and what does mod_security do? Anything bad turning it off?
