[solved] zotero item pane bibkey missing?

CitationUser

I am using Zotero 5.0.96 but suddenly the item pane, on the "Info" tab it does no longer show the bibkey. I changed several settings but don't remember which. How to bring it back?

The cite key has always been a feature of the better BibTeX add-on. Do you have that installed?

I do.

I installed the latest version 6 of Zotero. It is working now.

Thank you for your help.
