If you need support from Yola please contact us via email@example.com or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Conner is right, unfortunately you cannot edit the password protection page.
However you can create a page that links to the password protected pages - a landing page of sorts that you can customize to tell people that the rest of the site is password protected and to contact the administrator for details.
