[SOLVED] events are noot displayed

Hi Team,
was trying hard but cannot make the events published.
In backend joomla menu I chose for ex. "jem>category> I chose a published category and I expected that all events of this category are displayed in the frontend, but there comes only the message:  www.psychoanalyse-muenchen.de/archiv-oeffentliche-veranstaltungen-vor-01-05-2021neu
"Zur Zeit keine Veranstaltungen verfügbar" but there are tons of events aivailable and the same settings still work under Joomla 3. What's going wrong?
I expecailly want to publish all past events. In global settings I set "nichts tun" about past events and days "0". is thsi correct?
regards, martin

Joomla V 4.4.8
JEM V 4.2.2

Hi, Is it right that you made something before? update Joomla from which version, update JEM from which version? or something else.
Did you as admin change your id?
Did you used the simplelist settings to choose which categories?
You should exactly describe what you did to get your result!

Hi Jojo12, thnx, for quick reply!

I had the JEM comp also on Joomla 3 which is still online. see example:  archiv.psychoanalyse-muenchen.de/component/jem/category/2?Itemid=3776 . There it works with same settings, all events are displayed.

User ID is still the same "745"

I tried all kinds of different JEM neu items, also the simplelist setting, if u mean that. no display anywhere!

I upgraded the Joomla project fro V3 to Joomla 4 long time back already and on Joomla 4 I installed JEM again and all the events, whole database content is there. backend with JEM on Joomla 4 looks fine.

I created new event and new categroy in Joomla 4 but also no display.:  www.psychoanalyse-muenchen.de/testjem

I dont know what else u want to know about my result, I try again:
there is for ex.

1.  category "Öffentliche Veranstaltung" (see attach)
2. there are many events  in this category published......see attach
3. menu item: see attach
4. result: see attach and  www.psychoanalyse-muenchen.de/archiv-oeffentliche-veranstaltungen-vor-01-05-2021neu
5. setting see attach
 

Sorry, I was away, I had to teach dances, now I am back.
Your issue remembers me a problem I had years ago. It was something simple, but I can't explain.
It would be easier, if you could give me access to your backend. If you can send me an access via PM, I think I can help you.
I promise, I will only look and change nothing, then I will say you what's wrong.

I see in your backend screenshot, that the "Ersteller" is empty. It must be lost by some manouvre.Then the events will come
