Please check that string isnt incorrectly translated somewhere. If this is not the case, please update your access details on file and we can take a look for you

I am not seeing that issue on my own install here, after having checked this, so if you can provide that access, we can take a look if needed

I see that error on production site and on localhost with brand new, fresh install (4.6.9) as well.

 

I just tried to set up test install on my production host, but I cannnot change test install adres

There seems to still be an installation of Invision Community at the URL on file. Before you can change the URL, you must first remove the existing installation.

 

This url even doesn't exists....

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

With regard  your test install, it will not remove from your license when you remove an install. It has to be reset. We would expect people to be installing a test instance in the same location each time. If you do need it to be reset, please let me know
