Tried Andy Peatling’s suggestion of deleting & re-uploading the plugin, but still get the same fatal error in Admin > Plugins. (Running WPMU 2.8.4a + BuddyPress 1.1.1 + BuddyPress Skeleton Component 1.3).
Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot redeclare bp_example_register_widgets() (previously declared in /homepages/30/d119280860/htdocs/onesexfitsall/wp-content/plugins/bp-example/bp-example-templatetags.php:16) in /homepages/30/d119280860/htdocs/onesexfitsall/wp-content/plugins/bp-example/bp-example-widgets.php on line 65
