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!
All I can suggest is to re-add the code for your Twitter feed to your website. If it still doesn't update, I'd recommend to contact their Support for assistance. The code is just an embed code and therefore relies completely on Twitter's service.
