Hi,
We have upgrade the magento 1.7 to 1.9.2.4 through magento connect from admin. After upgrading the version everything is working fine except the configurable product when I click add to cart button it will show "504 Gateway Timeout - The gateway did not receive a timely response from the upstream server or application." for existing configurable products. But when we add new configurable product it will working fine. Please help us to resolve the issue.
Regards,
Viren Patani
