Random page suddenly defaults to ?foro=signin
My page https://authentic-self-empowerment.com/ase-supervision-group-session-videos/, which is password protected, is since today being redirected to our forum sign in page: https://authentic-self-empowerment.com/ase-supervision-group-forum/?foro=signin
See screenshot attached. I have not made any changes and am trying to figure out what might have happened and how to get the page back to the version where it displays the field to type in a password.
Any idea of what might have caused this would be most helpful and appreciated.
Accessing the link in the post above displays the correct page, and so does the "view page" link that is accessible in the WordPress editor when editing this particular page. Accessing it via a link provided in an email or pasting it into a different browser seems to produce the results from the screenshot - the forum sign in page.
