You don't have permission to access /phpmyadmin/ on this server.
When you see something like this, you realize that it could be a million things, and since I'm more of a hack then a web developer, I freaked out.
A lot of help forums suggested that you modify the alias information so that you allow access from localhost, like 127.0.0.1. Mine already had that setup, by default.
I was scratching my head over and over and couldn't figure out the root cause of all of this. Strangely, the SqLite manager was working just fine. This was so weird.
Then I went back and realized that the problem was that my C:\wamp\alias\phpmyadmin.conf file was just pointing to the wrong directory: it pointed to MySQL version phpmyadmin3.1.3 instead of phpmyadmin126.96.36.199. Ugh. WAMP team fail.
Check the directory and version number!
