strange warnings on plugin pages

Hi folks,

I’ve got a bunch of WP installations on my server. Each runs on its own domain name. Last night I was going through all of them to make sure that Akismet is installed and has a key on each of them. Strangely, I’m seeing messages on the plugin pages which refer to files on the other domains. If I log in as an admin on domain1, I see:

The plugin ../../../domain2/wp-content/uploads/2009/wp-db-backup.old has been deactivated due to an error: Invalid plugin path.

The plugin ../../../domain3/wp-content/uploads/2009/wp-cache.old has been deactivated due to an error: Invalid plugin path.

Those domains have nothing in common other than the fact that I have accounts on both and they both run on my server.

Any ideas what’s up? Maybe just that I hadn’t logged out of the previous domain?
