The version of EM is 5.1.7 and it’s the latest version of WP. I’ve tried deactivating all other plugins and also switched themes, but the same thing happens.
Is see now that the update sometimes work even though the errors come up. I therefor managed to get rid of the error on the location page which happened because one of the locations was missing a “locationimage” that was needed for my list.
But the other errors are still there…
