looks like the MediaMonkey theme is the default.
I can change to the prosilver theme, but config is only active when I am signed in.
So any guest browser gets the broken behaviour.

Maybe change the forum default to prosilver in the meantime?

MM Sites are going thru full Server migration and components updates.

Priority is to get all migrated and back online, while keeping 18 year old DB and data safe and accessible.

Sure we will make announcement. UI is quirking a bit, but we are handling it.

Thanks.
That alternative theme will take some time to become attracted to.
If you remember could you post here when it is fixed?
Is there a plan to fix it? Or has the recent extended outages reduced the appetite for further tinkering with it?
Is there any improvement with this new version? ... better image handling?

It's working for the prosilver theme. The team is aware this is missing for the MediaMonkey theme.

The new forum s/w seems to be missing the breadcrumb which displays the forum name.
ie. look at this post, it is missing the breadcrumb button/title at the top, where I could see which forum this post belongs to, and so I could return back up to the forum by clicking on it.
