Website Builder Blank, no design, help needed

Please see attachment. That is how my website looks now. And when I click to Edit, it has a very small sidebar that takes a really long time to go up and down. And there's nothing on the page. Any recommendations?

I just updated my domain in the past 48-72 hours so I don't know if that has anything to do with it. Thanks in advance!

Please post the URL for a page on your site where we can see your issue.

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.
