I have just noticed that when an instance of FV Player is on a page of any kind that the Mobile Menu, BuddyPanel Menu, or the extended Menu of the BuddyBoss Theme will not open.
All of these will open before you start a video. Then after a video has been played then will not open unless you refresh or leave the page.
I deactivated all plugins and was still getting the same result. Here’s a page where you can see this happening.
At this page the Mobile Hamburger Menu won’t open after you start playing the video, and at a certain width the Header Menu which shows 3 dots which can be opened to extend the menu that is hidden due to width constraint, will not open either.
Let me know what you think.
