This topic mentioned the same issue of not being able to deactivate buddypress 1.0.3 plugin after upgrade. https://buddypress.org/forums/topic/fatal-error-after-upgrading-to-wordpress-mu-282-and-buddypress-103

I tried as per your suggestion but it doesn’t work. BuddyPress ver 1.0.3 still cannot be deactivated.

After deleting the entire BuddyPress directory and refreshing the plugins panel, the plugin didn’t shows up (display blank) but the word “Deactivate” is still shown and upon putting the cursor over it, it is “www.mydomain.com/wp-admin/wpmu-sitewide-plugins.php?action=deactivate&plugin=buddypress/bp-loader.php&_wpnonce=1a9adedb1e”

I tried on another domain with an upgrade of wpmu 2.7.1 to 2.8.2 followed by a fresh install of BuddyPress 1.0.3 and the same fatal error happened when I tried to deactivate BuddyPress in plugins panel. I did the same suggested recovery/resolution but the error persists.

Any other approaches I can try? Thanks.
