Thank you for your help, but isn’t it crazy that this happens? I went from 300 visits a day to 30 because of this problem…
Then with each theme update I have to reciprocate everything again… it’s quite absurd this situation.
So you recommend that I change everything with product.url and I should solve the problem? As it seems to be just that…
Can I ask you if you can give me a check on the fly on my site https://cartonlineitalia.it ? I use screaming frog and I see that the first entry I get as an error is this one: “Canonical, transformed to canonical”
Thank you very much !
