I'm having problems with comments on my site. Anyone trying to comment gets the message;
403 Permission Denied
You do not have permission for this request /wp-comments-post.php
even if it's me and I am logged in as an admin. The site is not the primary site on the network, and other network sites allow commenting as normal.
I don't think it is a plugin problem as I've disabled them all and no change. However it is the only domain mapped site on the network.
Looking at my .htaccess file, its permissions were set to 0404. Is that normal? I tried setting them to 644 as per the codex article but again no change.
No comments have been possible on the site for 3 weeks now, any help appreciated!!
