Plugins not showing on dashboard?

I had the same problem the site I was developing was utilizing this plugin to show gallery on the homepage. The first few days the site was working well but when I launched a persistent white screen of death error developed.

I used the FTP access to rename the plugin file to something like(old_plugins) in this directory wp-content/old_plugins. I refreshed the site and realized the site as back and therefore concluded its a plugin problem.

I started sorting them one by one…when I came to Next Gen when I activated it the white screen of death error was back.

I simply deleted it and the error was gone. When I researched about the bugs of NEXT GEN I realized that even the plugin author acknowledges they released the latest version (2.0.0) with several bugs. http://www.nextgen-gallery.com/open-letter-to-the-nextgen-community-from-erick-danzer/

The root problem is a conflict with other caching plugins, esp nextgen plugin from version 2.0.0

I hope that helps.
