Yesterday I installed PhpMyAdmin on my Ubuntu 10.04 server but when I came to test it out I couldn't get it to work: I just got a 404 Not Found page instead of the PhpMyadmin login page. I searched the web and followed up several possible solutions but they all eventually just fizzled out. Then the answer suddenly came to me while I was watching this video: I had omitted to select the configure for Apache option during installation. I remembered just assuming that Apache would be the default and just hit Return without thinking, but watching the video made me realize that you had to explicitly mark Apache with an asterisk before hitting return. Simple, and I am rather annoyed that I fell for this.
