I have Silverstripe running on a LAMP server for approx six months. I was using MySQL workbench but I would like to use phpmyadmin now.
I installed phpmyadmin on my LAMP server recently i.e. six months after Silverstripe.
I have some modules in my Silverstripe server:
swfupload, GoogleAnalythics, youtubeservices, twiterwidgetpack
that's the only real unique thing about it. Otherwise it's a standard install.

My new install of phpmyadmin always brings up a blank white page when I call the alias i.e. http://www.mydomain.com/phpmyadmin
I can make an entry in the index page of phpmyadmin i.e. echo "test output";
I do see my echo when I call the alias but everything else is blank. Error reporting is on for php and Silverstripe works so the php configuration is OK. I have been testing one thing at a time for 3 weeks now with no progress.
