I am using magento 1.9. Everything is working fine. I purchased one module name as vss_oneclickchekcout (Buy Now). Its functionality working fine as I can directly purchase product on my site. But if I check product page url in google pagespeed insight then for the product page url it is displaying as no page found (404 Error) but page is accessible on my site. Same as when I disable the vss_oneclickcheckout(Buy Now Plugin) then in google pagespeed insight proper performance review is visible.
