I started the Product Levels free trial on my site. After adding it, if I try to modify any ATUM field on a product, when I click to update, all of ATUM fields get blank, without content. Also, I have realised that of my products disappear from the ecommerce pages, categories, etc.
I have been testing and if I desactivate de plugin (product levels) I can edit all of ATUM fields without problem, and it saves the field content although I re-activate the addon. Also, if I mark a product as a raw material or a product part, the product doesn't show at the Manufacturing page. But if i desactivate and reactivate the addon, it shows well.
I am using the last version of all the plugins. Have tried with only woocommerce, ATUM plugins and YITH plugins and I still got the same issue.
