I have a http://domain/ . The LAMP installation guide on the ubuntu site is incredibly easy to follow and I have only experienced my issue this one time...
when I navigate to domain/phpmyadmin I'm getting my sites homepage. My .htaccess file has ErrorDocument 404 / which is redirecting it. I'm not sure what I should check to fix this. Like I said, I've never had any problems until this installation - my .htaccess + phpmyadmin never gave me a problem before.
I've tried reinstalling phpmyadmin using synaptic package manager, which usually fixes these weird missing file situations.
Any suggestions? let me know if you need more info..
Thanks!
