Failed to "Save and stay" on product

[Alvarosc]

Good morning everyone!!

 

For a couple of days I have a problem with Prestashop. It happens when I save a product. I add features, description, etc ... and most times, when I click "Save and stay" the web goes to the list of products and the product is not saved.

 

Sometimes it works perfectly, saves and keeps you on the product page, but most of the time, it discards changes.

 

I've seen a user with this problem a couple of years ago: https://www.prestashop.com/forums/topic/300619-solucionado-error-en-backoffice-al-guardar-y-permanecer-en-producto/ His solution does not serve me because I already had precisely max_input_vars a high value (about 7000000) because I had already had problems with the translation page (I have many words to load).

 

I also saw this solution: https://www.prestashop.com/forums/topic/563074-can-only-edit-save-products-sometimes/?p=2429096 but my form.tpl has no such lines to remove.

 

Does anyone know any other solution?

 

Thank you very much!
