@robdeluxe I do remember something that happened to a few users and it’s a thing that applies to any plugin that has form fields. Sometimes, if you have a form that is too large and has more than 1000 fields (including hidden ones) and you have the default value for max_input_vars set to 1000, then the information from the submitted form will be incomplete. Please check the following post which is related to WooCommerce, but, as I said, it applies to any pages that have a lot of fields in the edit post/page form): https://docs.woocommerce.com/document/problems-with-large-amounts-of-data-not-saving-variations-rates-etc/
It could be a few plugins combined that together have more fields than the value set in max_input_vars.
As I haven’t heard back from you and this problem wasn’t reported by other users, I’ll mark this topic as resolved. You can still reply to this topic if you feel the issue is from something else.
