"The URL is the same as what you tried to change it to"

The plug-in shows this error when trying to change the URL, all though this is not the case.
The URL is the same as what you tried to change it to, so it has been kept.

What URL are you changing from and to?

[tobidwest]

I was trying to change it from empty to blog.herderzeitung.de/?utm_source=hz_shorturl_home.

Try adding https:// at the start of the URL. If that doesn't help, what browser & OS are you on?

[tobidwest]

This does not solve it. Chrome / Windows 10.

I see. And when you go back to the page after clicking save and getting the error (select it from the menu rather than just refreshing the page), is the field still empty?

I just repeated clicking "Save" a few times and it seemed to work this time. I think this issue can be closed. Thank you for your support anyway :)
