When I rose a support ticket of the forum I didn't expect the problem to be solved within 24 hours (I didn't put any high priority because this was a minor issue).
Support team repled within several hours and immediately provided a workflow for a solution. It didn't help however, so they immediately took over my installation directly and the next day morning the problem was solved. It resulted to be a bug on their side (should be fixed with the next release) but they applied a fix to my installation themselves.
So, this Wordpress theme and the team behind it definitely worth the money we have paid for it. I give my "5 stars"!
