Can not test all functions for all the updates Wordpress and Appthemes do, i would be doing nothing else.
I love to help out you out but please read this first Have you tried to install in a root domain? Have you tried to Resave permalinks? Have you tried to disable all plug in? Have you tried the default theme of Wordpress?
++ If the issue is fixed consider closing the thread and change to solved, thank you for helping us helping you. ++
Thanks for confirming then. By the way, I like the simple clean look of your site.
Please help our moderating team work more efficiently by not sending us support questions via PM. You can read more about how AppThemes support works here. However, you can send a PM to follow up and remind me if I missed your support request/thread.
