I have picked up your other thread, too, and it looks as if the issues are likely related.
First, please check your browser console: I would expect to see JS errors on these pages. If so, please share details.
I don't have any details of your site, please share debug info in your next reply (hidden link).
Could you please try disabling the non-Toolset plugins and switching theme to twentyseventeen or twentynineteen then trying again? If the issue disappears then it should be possible to determine the source of any conflict by a process of elimination.
Let me know how that goes so I can see how to proceed.
Nigel, hello.
It seems to me problem resolved.
I went to Toolset debug information, and saw at the Troubleshooting section button "Delete leftover posts". After clicked this button, now i can edit view. I attached prtscreens. If problems come back, I'll let you know.
Thanks a lot
I re-opened the other thread, and am requesting the same here, namely basic debug steps.
Can you disable all non-Toolset plugins and switch theme to twentynineteen0 and then test the issue again.
If the pages are working properly it would point to a conflict between Toolset and one of the plugins or the theme, which you should be able to determine by a process of elimination.
