Hello,
Support staff has access to support forum only. We don’t have live chat or call center.
Besides, is this your production site or staging site? If you have production site without an updated theme could you, please, provide us with link? We need to check the layout you had before the update. Or it would be better if you remove the existing staging site and make a full copy of the production site to staging without update of plugins, WP and theme (using Duplicator plugin or any other suitable for you way). We’ll log in to this new staging site and update theme to 5.x version first and then to 7.x version. Update to 7.x version from 4.x reset the options and we can’t restore them even if downgraded parent theme. So, we need full working copy of the production site without any update to proceed. Could you do that for us?
Regards
