All articles have their unique id (UID).
I switched to the default template for testing, and it still does not 
work. What makes me curious is the fact that the problem appears only 
when I try to add the item to the basket on the SINGLE view page. When 
I'm doing this on any other page type (LIST, LATEST etc.) it works 
without problems.
