I’ve had similar problems with certain plugins. I just installed “Audio Player” and now frim the admin console my plig-ins page is blank. So is my Askiment page and the Widgets page.
I’ve deleted the Audio PLayer directory from the Plugins directory via FTP (whiuch usually works when other plugins do this). But not this time… I can still get to the “add new” plugins page, but not the main plugins page. This makes it impossible for me to individually disable plugs to see which one caused the problem.
I’m running WordPress 3.0.1. Any ideas?
