Update:
I am trying to upgrade from 7.4 to 7.8.
My 7.4 version displays subpanels correctly.
After upgrade to 7.6.6 everything is ok.
But upgrading to 7.8.2 or 7.7.9 hides all my subpanels in “Suite P” or “Suite R” themes. Can anybody help me? Thank you.
Browser console is full of repeating messages that look like:
Uncaught TypeError: Cannot set property ‘className’ of null
at Object.updateSubpanelTabs (SubPanelTiles.js?v=2D_Q458oAGSdQw-2dS0ygQ:142)

(See screenshot attached)
Is it related to my disappearing subpanels? Any ideas?
Thank you for your reply.
All the common methods you mention I have already applied with no result.
The way subpanels become visible for a while and then disappear makes me think that the problem is a javascript. However it’s looks strange that the theme matters.
