The first the I see that stands out … You need to enter the original in English not the original string in German. Sorry, nothing I can do about that. It is just the way WordPress handles swapping strings.
With that said…
Add My Directory Entry
Do you have the Form extension installed and active? If you do, the text domain will be ‘connections_form
The original string must be
Biographical Info. There is no text domain
connections_manage so you should delete that.
I can not tell from the screenshot which you’re trying to change, but you need to enter the original string in English.
There is no text domain
connections_slim, so that is not going to do anything. If you’re trying to change an address type label the text domain needs to be
connections and the original string in English.
Hope that helps!
