Kash’s products are usually bullet-proof, at least as much of the products like this are on the web.
The ‘disable thumbnail’ fix worked on my site with the free version. On my paid version sites, I restored my WordPress install using a backup tool on my host, Siteground which worked way easy. The last update for me was Dec 3 at 2.55 PM. Not sure what timezone that is. Maybe Eastern Standard.
I also set my WordPress to no new upgrades for the time being.
Best I can do with my limited skills here.
