Customer review malfunction

[mixglo]

I tried to view my item's listing page but experienced problem to load the page completely as the lower section of the page could not load customer's reviews successfully.  Thought I should turn off the customer's reviews but could not find where the setting is.  Could you please help me to locate the reviews setting?  thanks.

Thanks for your help.  I saw the option to turn off the customer's reviews so the page loading is not a problem now.
But I tried to select item but could not adjust the quantity.  Is there a new problem of my item listing?
