I have been using 2.5.1 for about a month. Everything was working fine until yesterday I tried to upload a new post and a new screen came up saying:
"Forbidden
You do not have permission to access this document."
I think it is a 403 error. I have tried using:
<IfModule mod_security.c>
SecFilterInheritance Off
</IfModule>
.htaccess in the wp-admin and root directory.
Still nothing. I need to get this up and running asap. Can you please help?
