I have an error when I put more than 12 or so ranges to my carriers. I have one carrier with 10 ranges and it works just fine. The problem comes when I try to put more ranges. I tryied to delete the carrier and start over but it keeps showing the same error again and again.
I don't know if someone has found the solution for this problem or knows anything that could help.
My version of Prestashop is 1.7.7.5
Thank you so much!
