In my relatively new TYPO3 installation (Version 10.4.9) I wanted to add some backend users that do not have admin rights. When I login as a recently created backend user that has no admin rights and click on "pages" the following error occurs:
"Page tree error" "Got unexpected response from the server. Please check logs for details." / Seitenbaumfehler "Unerwartete Antwort vom Server erhalten. Bitte überprüfen Sie die Protokolle für mehr Details."
In the protocol of TYPO3 there are no errors documented. When I give the user admin rights the page tree shows up with no error. Clearing caches does not help. I found out that there was the same error in an earlier version but it should have been fixed in the 10er version:
Typo3 update 9.5.16 Page tree error for non admin users
Has anyone a suggestion how I could solve that problem?
Thanks!
