i experience the same issue… but i also read this on line 19 of the php file

wp_schedule_event( time(), ‘twicedaily’, ‘bp_groupblogs_update_all_feeds’ );

I suppose this means “refresh the output every 12 hours”.

Perhaps try to load a thread that is (surely) hourly updated to view if something changes in your plugin output ?
