Hi, im coming back with a similar issue from years ago. Renovated the site www.lamanzana.coop and strange things happen when trying to buy fractions like 0.250 kgs., it says a nonsense message that the closest valid values are 0,001 and 1,001, so it doesn let put nothing but that. Then if i go to the cart, it overwrites the value with plain 1.
Maybe there`s some woocommerce update that is causing this conflict? i have no strange plugins functioning, and when turned everything off, the issue continues.
Atum its configured with 3 decimals and 0,01 in steps, like it was on the old site where it worked fine.
I would appreciate your help very much, please let me know if you need more info or credentials.
thanks in advance.
