Hi,
this is a very weird behavior that i started getting after updating to version 4.5.3.
One of my products actually shows in the “add-to-cart” section of the page information regarding another product that is in the same category.
The description, reviews,etc are all correct. It’s just the upper section with the price, start reviews and small description that is wrong.
While trying to figure this out, if i change the category of the product whose information is showing to another then it it shows the correct information. But, i can replicate the problem with other products by simply changing their category.
This is very weird.
I came to the conclusion that the problem was the theme because when i change one of the default themes everything works fine.
