It is a strange thing! Here's a little recipe that works 100% of the time at my website.
1. Open the list of JEM events (assuming there is at least one).
2. Middle click an event, to open it in second browser tab.
3. Open the "Global check-in" page (System -> "Global check-in") in a third browser tab.
4. Reload the first tab (list of events) to see the padlock indicating the event is checked-out.
5. Reload the third tab to see that there is an item that can be checked-in.
6. "Save and close" the event in the second tab.
7. Reload the first tab to see that the padlock is gone.
8. Reload the third tab to see that there is still an item that must be checked in.
So JEM thinks the item is checked-in, but Joomla does not? Checking in the database with
Code:
select checked_out from XXXXX_jem_events where ID = NNN;
shows a nonzero value from step 2-5 and a zero from step 6 on, so I would say that the item has been checked back in. Am I right?
Maybe it's a bug in Joomla. I found issue 41149 at the joomla-cms github. It was filed against version 4.3.3. (Sorry, for some reason I can;t insert a link.)
