“my checkout page is showing the obox facebook version of checkout on my main site instead of my sites checkout page …. when you go from cart to /checkout/ ”

Note: the issue with the SC detection causing a similar issue has been fixed in 1.1.5. Please be sure to update your plugin.

The Solution

This issue seems to occur due to how cookies and caching are handled by your browser. If you visit your Social Commerce checkout page in Facebook, then go to a similar page in your main site shop, the Facebook layout will be shown as the cached layout.

To resolve, clear your browser cache and then access Facebook again.
