I switched hosting and I’m currently using wordpress 3.0.5 and buddypress current version when I go to login at my http://hairremovalreviews4u.com/wp-admin/ login my screen goes blank Ive read about deleting plugins and reactivating them but how exactly do you do that from your files. Can Somebody list step by step instructions and other options in case that doesn’t work I’ve tried erasing everything and reloading from my backup but that doesn’t work. I’ve checked mysql database to make sure my files were loading correctly and all that info was correct my current mysqul version 5.0.83. Php 5.2.12.

The weird things is when I go to my main site everything looks like it works fine I just can’t log into admin. http://hairremovalreviews4u.com/ I’ve gone through this forum read about increasing memory limit and deleting plugins and reinstalling but doesn’t seem to be working. I havent altered any core files or made any changes to the wp-config file other than making sure the right mysql databse was being loaded dont have too much php knowledge but im familiar with html and css if I need to edit code I can do that if somebody list detailed directions. Thanks for the help
