Error 404 on Dynamic pages

Question:
All of our websites have suddenly started producing Error 404 on dynamic pages even though we haven’t made any changes. The URLs are correct and if we keep refreshing the page it eventually loads.

Product:
Wix Editor

We have already reported this and it was escalated to the CMS team, but nobody has got back to us. Can anybody from Wix help me to get this resolved asap?
