I’m not sure if this is linked to GeneratePress so apologies if I am posting this in the wrong place but I thought maybe I would post just encase it is a known issue.
I have a problem where the products disappear from my Woocommerce store approximately once a day. They just disappear from the Woocommerce shop not from the backend. To get them back, I just have to go in and update the product permalinks settings then they return (but I have no idea what’s causing it to keep happening).
not something we have come across before, can safely says its not theme related.
Sounds more likely to be a server / htaccess, cache or CDN issue.
Ask your host to check the error logs to see if any problems show.
