Prestashop 1.6.1.8 URL structure

[markovo]

Is there some changes in Prestashop with this version (1.6.1.8) that changes the URL structure?

Here is an example from working Prestashop store (1.6.0.6)

This is the URL structure to a category : www.xxx.com/category/subcategory/sub-subcategory

This is the URL structure to a product : www.xxx.com/category/subcategory/sub-subcategory/product

Here is an example from working Prestashop store (1.6.1.8)

This is the URL structure to a category : www.xxx.com/category

This is the URL structure to a subcategory : www.xxx.com/subcategory

This is the URL structure to a sub-subcategory : www.xxx.com/sub-subcategory

This is the URL structure to a product : www.xxx.com/category/subcategory/sub-subcategory/product

So, there is no inheritance of the URLs in 1.6.1.8!?

 

All SEO & URL settings are the same (All Default, only Frienly URL is turned on in both stores). Are there any changes in 1.6.1.8 regarding this issue?
