I've searched and found people with this same problem, but I've had no luck fixing it. I installed ISPconfig without any problems and then installed phpmyadmin v2.x I didn't look carefully to notice that there was a version 3.x. So I made my next mistake by installing v 3.x on top of version 2.x and got the black page. I did some searching and found I was supposed to remove the old version first by deleting some files, which I then did and tried re-installing again via the update in ISPconfig. I then restarted the ispconfig service /etc/init.d/ispconfig restart. I still get the loading then blank page and phpmyadmin won't launch. Not sure what else I can do to fix this. edit: Nevermind, deleting the cache fixed the problem.
