I did some changes to CA and didn't save it. When I went to exit CA I got a prompt in what I think is German.
With two choices - Ja and Nein. I clicked Nein since I didn't want to save it but this should be fixed at some point.
what is the version of the 3cx phone system and what is the version of CA that you are using. Where you using english during this time in the 3cx management console when German suddenly popped up?
