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!
When you log into the sitebuilder there is a site file title on the upper right hand side: Select Site. This is in fact a drop down facility and by clicking on the arrow on the right of this title then the other site files that you have created will show as a vertical list. You click on the title you wish to edit and it will appear below in the Edit Site where you just click again on that button and the site file will open.
You can delete site files no longer required. The first thing to do is to Unpublish Site > Site Settings > Site > Publishing > Unpublish Site ( if it is in fact published), then you can delete the file itself. Site > Site Settings > Site Properties > Delete Site
