It has nothing to do with the user. I even cannot add with the GD user correctly (see my last test).
I will get you the FTP credentials

I will setup a XAMPP installation here in the meantime.

Okay. On the test server I was now able to add a place with location. I used MacOS and Safari on my laptop. Let me check my office PC (windows with chrome).
Typically, I don’t have a lot of plugins installed on the browsers.
Looks like it is a problem of my PC setup.

Okay. On my server it is working.

The difference what I can see is that the hoster is using different MySQL Version. As WP is running on the hoster database, do you have additional requirements on the database?

Let me also check scheme and char settings on the MySQL Server of the hoster.
