I've tried to reproduce the issue you describe on a development 21.11.09 instance that I set up, but was not successful.
So, I have a few questions for you to help me diagnose this ;-)
Assuming a package installation, have you restarted the koha-common service following the upgrade?
Yes, we have. We have also restarted the complete host.
Have you performed a hard refresh of your web browser's cache? (hit CTRL-F5)
Yes, we did.
Finally, which version of Koha did you upgrade from?
We have updated from Debian 9 to 10, then from Koha 19.05.02 to 21.11.09. Best wishes: Michael -- Geschäftsführer · Diplombibliothekar BBS, Informatiker eidg. Fachausweis Admin Kuhn GmbH · Pappelstrasse 20 · 4123 Allschwil · Schweiz T 0041 (0)61 261 55 61 · E mik@adminkuhn.ch · W www.adminkuhn.ch
