I don’t have any idea when an update may be released.
Before I restored my website a few minutes ago from my backup, I did a little experimenting, trying various things, such as importing the saved exported data from the Virtue theme options panel. No joy. All that did was corrupt the website database so that my child-theme style.css customizations wouldn’t work properly.
Not having the time to delve into solving the problem the hard way, I took the easy way and restored from my backup to get back to a working site.
I suppose if someone hadn’t made a recent backup, they might try uninstalling the Virtue 2.1.4 theme and its plug in, and then find a v2.1.3 of Virtue/w-plugin, (probably on the Kadence web site), and reinstall them. That might restore the website, if the website database wasn’t corrupted by the v2.1.4 update. Perhaps my website database got corrupted by v2.1.4 because I didn’t try that first. Instead, I imported the previously exported theme optionsdata, which is supposed to prevent you from losing them during an update, but, well, that just made things worse in this situation.
Good luck.
