When updating from Woocommerce 3.9 to 4.1 I get this error message. Not sure where to start, so I thought I would check with you to see if this is a possible problem with the theme, or if you have seen this at all.
I’ve restore the site to the old version until I can get an idea of what to look at. I can’t afford the downtime.
