Hello max122812,
This needs some debugging. Maybe it happened due to some recent change.
Do you have any recent backup? If yes restore it
Or else for some time put the site in Maintenance mode and ask your team/people to check on what changes are made.
Thanks.
Thanks, we still have not figured it out we disabled all plugins and notbing, but now our product pages are showing a not found error? Could this have something to do with permalinks how do we fix this?
