I have the same issue here. I’ve deactivated all other plugins (except page builder since tiny MCE work w/ that one!). Anything I input into the visual editor gets erased when I update page. I can create other non-MCE widgets when I have MCE deactivated and they will be correct after activating the MCE again though if I create the same when MCE is active it doesn’t work. The pages have ( it HAS worked til recently) a portfolio and a Bookly payment/scheduling plugin though it happens if there’s only one widget on the page. Tried with twenty twelve theme…still no luck.
WordPress 4.2.4
Siteorigin Vantage theme
latest tiny MCE
No error codes
Happens in Chrome or Firefox
