If you don’t see the preview you will have to refresh the page 2 or 3 times. Thank you for your great support

hi, i still have the same problem.
I switched to higher performing hosting with super caching in SiteGround, so it’s not a cache issue.

Sometimes they open immediately others I have to refresh the page at least 2 times.
I also thought about buying the PDF viewer plugin but I believe the problem will not go away and it will be wasted money.

Please guys, I need help. There must be a solution and I am convinced that you will find it as you always do.
Thank you very much.
