Bug with Go Full Screen
When this button is clicked, all page content disappears except for the top menu.
The only way to restore it is by deleting the browser cookies.
I tested it in three different browsers.
We have noticed it. We are going to release a fix soon.
Fixed in the latest version. https://community.wpmanageninja.com/portal/space/community-meta/post/fluentcommunity-1-7-1-release
