I see several people posting here about problems trying to get the automatic plugin upgrade to work in 2.6.
I'm having problems with every plugin I try to automatically update. In each case (I've done it with four or five different plugins), there have been error messages that the plugin could not be unpacked. Or, in some cases, the plugin is unpacked, then the screen says "Update completed" -- but it isn't.
Anyone fixing this annoying bug??
