Reading your whole topic (oh that was hard), i see you have a LOT of login/hide/security plugins, messing with permalinks (slugs).
I suspect all that create some issues.
You MUST enable debug to a log
and after a while check the debug.log file.
Also SOMEWHERE you have set as slug "community", somewhere IN WPFORO. Search where ....
And try to solve ONE BY ONE the issues. Installing some other plugin to cover some issue, will not help you.
Doing massive changes during an issue, just complicates things.
@dimalifragis only think, that I can try nie I think is unninstall and delete wpforo and try install it again. But I think, this way will be lost all my settings 🤔
Do you think or now about any toloc here about that? If it is possible to delete plugin and download again without losing all settings, topics, posts etc.? Thanks
Oo, I find it here, Thanks.
You should deactivate the plugin (NOT uninstall if you have some data), delete wpForo. Then find and install it again. In this case, the information will not be lost.
So will try it later in Day and let you know
I just write here that I try reinstall wpforo from advice, everything was OK, my settings and topics, etc., is still here, and also deactivate two plugins, which show DEBUG LOG error, but it is still the same.
I try also create again URL forum, and look at core wordpress DEBUG LOG, but cant see any other possible option, how to solve my problem.
I make screenshots here to look, because it is interesting to me that for example now, I restart wpforo, put shortcode on URL page /forum/ and everything was fine. I click on my profile, profile other members, their activity, favorite, etc., and it show great as you can see on screenshots.
But maybe on eight clock on my profile, suddenly again forum shutdown and only empty page as you see on screenshot and again, when I look to my wordpress pages, it create somehow new page with URL /community/. If i put shortcode "wpforo" here, it was fine for minute, I can cloick on profile, login, rehistered and again shut down - empty page - created /community-2/
So I really dont know and maybe, if some of the admin can take a look at my page, I will be very thankfull. I dont know, if it is possible and also, if I need to write email on your support, or just here?
And here is my sceenshots from 3 minutes of running forum greatly.
