Product Comments is not working

[Giordx]

Hi,

 

when I active the module I see in product page two more links, but no one of them is working well.

I see:

- add a comment

- write a review

 

Clicking on the first show the form to send a comment and stars, but the information sent are not saved on DB.

Clicking on the second I get a message: The requested content cannot be loaded. Please try again later.

 

I've installed PS 1.6.1.6 and the native module Products Comments v3.5.2

 

 

Any help is appreciated.

thanks
