The theme is full of bugs - I believe it is set like this in order to get more money out of support.
I love the design so it is a shame there are so many bugs.
We never charged and we will never charge extra money to our buyers for bugs or anything when users have regular and free support. We are a serious company! with serious people working here!
Regarding the theme and supposed bugs you talk, the theme don't have bugs, all reported issues are currently fixed on previous updates.
The problems you talk in our support page, are related to your server, not our theme, and with that, we can't do anything. Your server take more than 6seconds just to load the first byte http://dev.upperinc.com/blake/wp-content/uploads/2016/12/azurewebsites.png this is our fault? If you are interested on debate this, we are here 100% available to help you. Send us a email to email@example.com.
