If you need support from Yola please contact us via firstname.lastname@example.org 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!
Check the domain names in the sitebuilder for both of your published sites. You mentioned adding the address in the search bar. Not the best place for this try adding the address to the address bar above that. They have quite different purposes.
One possibility is that your second site is re-directing to your first site. You need to check this out also.
