Hey, I upgraded to WordPress 2.7.1 today (from 2.7), and while the plugins themselves are still working, they are no longer displayed under the Plugins panel, i.e. I can't activate/disable them. The only way I can disable them is to delete the actual folders from my /wp plugin directory.
I took a screencap of the page so people can see what I'm talking about:
Any suggestions on how to resolve this?
