Thanks for your quick fix. Now it works as a charm.
Only on more thing. When I enabled all my attributes in Attributes menu manager the visibility of available menu items has been reset to display all available items (Prices Filter, Articles, Products, Services, Testimonials, etc…). Maybe a small bug but nothing harmful.
Have a nice day and thanks for useful plugin.
With all honours, _smarty.
PS: I changed my rating to 5*. ??
