For an unknown reason when a manager (not an admin) tries to edit some contents in backoffice I get this error message:
Data integrity check failed, you are not allowed to save this item. For
security reasons, you can't edit more than one content (from the same
Content Type/Form) in different tabs of your web browser. An error has occurred.
however I can garantee that there is NO other content edited by this manager in the web browser. The error is elsewhere.
Here are some additional infos:
the error only occurs on some contents
if I edit this 'faulty' contents as an admin and then try to re edit is as the manager, the error disappears
If I set this manager user as an admin , the error disappears
there is NOthing locked in the whole site
I use J 3.9.4 + seblod 3.17.3
If I remove ALL the fields in the admin form, just leaving the title, the error remains.
