I have recently set up the reviews and it worked fine until about a week ago and I have not made any template changes.
The only difference is that the database is being populated by more and more products.
Reviews is integrated with VB
and I use the VB
I have installed some new products in VB
if that could be a problem, vbgooglemaphse and Links and Downloads Manager.
