I've done everything you suggested above and checked my config file doesn't have a password (as suggested in another thread).
I still get the same issue, I open phpMyAdmin and get a log in screen (not the page indicated by your screenshot) I leave 'root' as the user and leave the password blank to login. I get a blank page. The url bar reads: [
localhost]
Any other suggestions?
I am running Win XP and Firefox, incase this is relevant.
