Huge problems with theme

Hi,

Earlier this year I bought the Enfold theme for a costumer, installed it and everything worked perfected. Now, I’ve bought the theme again – this time for my own website. But I’ve run into so many problems, that I really need som help to get things going:

First of all, I can’t see previews of what I’m doing. I get the message that I do not have the permission to see them. Therefore I work on the live.site, which is far from desired.

Secondly, When I change elements on my frontpage, update the page and go to the livesite to look at the result, then, when I go back to WP, the changes has not been saved. After reading your supportforum, I’ve tried to deactivate my plugins, but it deosn’t help. Also, some of the plugins are part of the overall design, so I need to activate them at some point.

Thirdly, when I choose icons from the lis,t i.e. on bottons, the icon changes to a Chinese sign on the livesite

I’ve been trying to work around these things since yesterday, but I have to give up. I’m not much of a code expert or anything, so I’m kind of lost here. Also I wonder why I didn’t have all these problems when I last worked with the theme?

Could you plese help me in any way?

Cheers
Malene
