Yesterday I upgraded our site from 3.6.2+ to 3.7.1
Today it was noticed that since then for some, but not all, site admins the Administration block on the home page is empty (see attached pic).
The users can access the Site Admin functions by going to the /admin URL directly so it appeared to be a problem with the Administration block rather than security etc.
Delving a bit deeper, the menu is being rendered to html but its parent card is then getting set to display:none in the css. If I disable display:none the menu pops up as expected.
I've attached a screenshot of the page's developer tools. I think I'm now at the limit of my bug fixing ability on this! Has anyone else had the problem? Any idea of a fix?
BTW I've removed the users from sysadmins and re-added but to no avail, I also added "$CFG->siteadmins='2,15,335,402,25,186,334,554';" to my config.php but (as you'd expect) it made no difference to this problem.
