Regarding, product url path..

[hgati]

Hi, Thank you for the useful extension.

The entire product line has been reported to have issues. What could be the problem?

It doesn't seem like there is a specific problematic URL.

Hi @hgati

Be aware that url_path and url_key product attributes are something different.
See here and here where we've already explained before why url_path's for products (not for categories!) are bad.
