I typically download and install plugins via FTP, but I have installed a few from the web interface. I am trying to move WP from remote to local and I am getting a blank wp-admin screen. I think its one of my plugins causing the problem. I have renamed wp-content/plugins to wp-content/_plugins to disable all the plugins in that folder. But I have plugins installed that do not appear in the plugins folder which I believe are causing this blank wp-admin screen. Please advise.
