Does not work. I removed cookies, removed cache. Tried browser i never used for zammad (edge) but i cannot set tags. Version shows "Dies ist die Zammad Version 3.5.x "
That does’nt fix the Problem.
In Firefox, it looks like the tag is being saved. If you close the ticket and open it again, the Tag is gone.
In Chrome(ium) the page is reloaded when saving and the tag is gone.
If we would merge two Tickets, we get this message
