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!
Unfortunately, we do not have a "one click" solution to change your font site wide.
You will need to change them manually by selecting the text and then using the text toolbar, applying your new font face.
In the future though, if you would like to continue with the font you have selected, you can do a "save page as" (click on the arrow beside "save") and give this page a new name. This will replicate everything on that page including the font. Then, you can delete and add widgets as needed to build your page.
