Hi André a11n,
thanks for your reply! We have this problem with 3-4 WooCommerce Installations. If i disable the plugin the error don’t appear.
Last year we changed the Server and get a upgrade to MariaDB – can this be the problem?
Is it possible to export all Woo-Settings (and Data) and do a new install? I can’t find a Plugin for that…
Greetings
Henry
