When activating "Toolset Views" javascript errors and display: none; appeares in Settings Page of Flatsome and javascript cookies errors in wordpress occurs!!!
We already have a report of this conflict with the Flatsome theme. It appears related to Maps as well, not just Views, and I note from your debug info you have it installed.
As this is just affecting the Flatsome admin pages for now the only option would be to temporarily disable Views or Maps while you make changes to your theme settings, then re-activate when done.
I'm escalating this thread and attaching it to the existing internal ticket, and I'll let you know if there are any developments.
