Hi @smart_x,
I apologize for the information in the screenshot. We’ve removed them. I’ve taken a look at your site, and it isn’t uncommon to run into quirks like you’re describing with a complex site running many different plugins like this. What I would recommend doing is testing for a plugin conflict by disabling other plugins temporarily to see if the behavior you’re having in Pro stops happening.
Also, I did notice an error that is effecting the preview frame from working correctly. Somehow your site is outputting additional code after the closing HTML tag. Looks like you are adding it via footer.php in the theme.
You could simply move that code to the Javascript code editor in theme options. I don’t know if this would cause the problem you’re seeing, but it could cause conflicts with scripts running in the preview frame.
