This is happening to me today and it makes no sense. Can someone help?

Folks please post the URL for a page on your site where we can see your issue. SS has recently updated their forms so there may not be much we can do, except perhaps report some problem edge cases.

A link to the backend of the your site won’t work for us, i.e. a url that contains /config/.

Please set up a site-wide password, if your site is not public and you've not already done so.

Post the password here.

Adding a site-wide password does not allow anyone to alter your site. It only allows those with the password to see your site.

Please read the site-wide password and how to share a link documentation to understand how they work.

We can then take a look at your issue.
