The theme has just been updated to version 1.6.1 1.6.2. For full details check the item page where an updated change log has been posted: http://themeforest.net/item/mingle-multipurpose-wordpress-theme/235056
Update: August 9, 2012 – I just saw that the 1.6.2 update has been approved. I didn’t get the confirmation email yet but it’s no longer showing in the queue so that should mean it’s ready to download.
NOTE: Two files were not listed in the change log by accident:
framework/theme-functions/buddypress.php
style-default.css
If you’re only copying the modified files you should include these as well. I’ll correct the change log on the next update. Thanks and sorry for the mistake.
