@yisrael-wix In your screenshot above, you have a menu command/option named “removed from main menu”, when you clicked on my HOME page. I understand that you are a top tier Dev and Admin and you may see things that end-users do not. And I’m glad this is happening in terms of system stability, integrity, etc.
The thing is, as already reported to and confirmed by a Wix Support Expert on chat that I contacted for another matter of mine earlier, that she couldn’t either understand why I can’t Hide Pages in Site Menus and why this option disappeared from where it normally resided all this time. She mentioned nothing about UI changes.
At the moment, I have disabled Menu navigation in my site. I have (I had, I deleted them) quite a few test1, test2, testetc pages or half-prepared ones that should not meet the public eye. Those, I can’t hide and as such, with all due respect to your personal efforts, I don’t have a good site and sure “not good to go”.
edit 12/29/2020: after some more research, it seems that the apparent coincidence of changing the UI and having my site crashed for 3 days, at the same time, led me to believe that ‘Hide’ option disappearance was somehow related to the crash. Anyway, still this option can’t be found anywhere near to where it was 3 days ago, but indeed, the functionality is now found inside ‘Manage Menu’ button in Menu properties button pane. Thanks @yisrael-wix for being on top of this matter and thanks for helping me one more time.
