georgef101, do you still have the bp-themes folder located in wp-content? If so, BuddyPress will think you’re using the old theme style and look for the 1.0 avatars. If not, make sure your folder permissions are set (I put mine to 777 to make sure it works, but you may want to do 755 depending) and then run the code above. It should rename all of your avatars accordingly and put them where they belong. Once that’s done, you shouldn’t need to delete or change anything.
