RE: the Sherlock theme - none of the changes that I make with WPBakery Page Builder saves, either in demo pages or new pages. I've tried deleting elements, changing elements, and adding new elements. After updating the page, it just reverts back to the original state. Please let me know if there is a fix for this behavior. If not, I'll be forced to request a refund, as it is presently completely unusable.
Sorry to leave this message on a forum - I was hoping to resolve this through a more discreet ticketing process, but I could not locate that option, if it exists.
