I was getting errors on posting comments on the blog here.
“You don’t have permission to access /wp-comments-post.php on this server.”
So I started looking. Things were working fine before and I was getting comments just fine. Then I switched the theme to something else and it apparently killed things.
So the request was blocked.
To fix this…
What you need to do is go to your WordPress dashboard -> Security -> WordPress Tweaks.
Once you’re there you need to uncheck the Comment Spam checkbox and save it. Comments will once again work!
