I have a brand new install (not premium) and have exactly the same problem. Facebook and Twiiter, no problem. Instagram accepts authorization but won’t complete post saying no authorization.
@fish911 – I never received any reply or support, so I’ve abandoned the theme and went to something better supported. Sorry.
I am having the same problem with this theme on a clean site (no other plug-ins installed).
If you have a top menu item with no sub-items, the navigation works fine – click on the top menu item and it opens.
However, if you add a sub-item to the top menu item, it will not open the top menu item.
You can look here for an example: http://www.newschoolmontessori.com/dev/
Thanks for any support,
Joe
