I am logged in as the admin on my site but for some reason whenever I try to delete a post it stays there and this message appears:
You don't have permission to do that.
I am the only user. I found a post about a similar issue from seven months back but it seemed to have been resolved.
If it's any help, WP is installed at mydomain.com/wordpress/ and I have configured the blog to be at mydomain.com.
