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.
