I had the same problem. The wordpress was updated to 3.6.1 but the theme was still at version 1.7…
Is there any fixes for this? I am going to try to do an update of the theme for which i have never done before and I am wondering if i need to rollback to the 3.5 wordpress as it lists that is compatible with up to 3.5 on the product page for the Ability theme…
