Blocked facebook referred links (htaccess/mod_security??)

Hi everyone,

I’ve done plenty of research on this, and think I know what’s wrong – but I’m having problems implementing the fix!

Either with 3.0, or because of something my host has done recently, links to my wordpress blog referred through facebook are met with a 403 error!

Research suggests that my solution has been posted already here.
The last post by gonzalezea hits the nail on the head.

So I need to modify mod_security via htaccess like so?

Okay, here’s where I have problems:
– My blog is installed in a subdirectory on my website
– there’s no htaccess in the blog subdirectory
– if i create one, it doesn’t fix the problem
– There IS an htaccess in my website’s route directory (does wordpress refer to this file instead?)
– if i add the required code to that file, it doesn’t fix the problem

So I’m confused as to how I should edit mod_security. My host uses cpanel, but I don’t think I have access to WHM.

I feel like it should be simple now, and I’m not a completely basic user, but I’m stuck!

My blog gets a lot of traffic through a related facebook group, so this is kinda important to me!

Thanks a lot!
