When I try to access a post with “phpmyadmin” in the title on my WordPress site, I get a 403 (forbidden) error. After digging around for a bit, I realized that the issue was in the permalink and that replacing “phpmyadmin” with “phpmyadm” made the post accessible again.
After some more thinking I figured out that the reason was that I had set up a rule in apache\conf\httpd.conf to deny access to phpmyadmin from most IP-addresses. The rule looks like this:
<Files "*phpmyadmin*"> order deny,allow deny from all allow from 192.168.0.50 allow from 127.0.0.1 </Files>
So, this rule inadvertently triggered on the permalink and denied access to the post.
Maybe someone else stumbles upon this problem and is able to google up this explanation and solution.
