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!
This only happens in the Yola Sitebuilder Preview mode, and it is an error that we're busy fixing. Once you published your website, it should work on your live site. Please check this, and let us know if it doesn't work as designed on your live site.
