New upadate crashing website on checkout

[nichinu]

Hey, I just installed the new update 3.1.0 and it just messed up mys business. The website works fine but just on clinking checkout it crashes with 500 server error. I uninstalled the module from the admin and cleared modification but the FBE was still there. So i jhad to uninstall the module's settings as well. Please look into it and also provide me the earlier version 3.0.1.

Thanks

Hi, as Facebook Graph API doesn't support HTTP2, it has caused issue in your webpage (which is on HTTP2). https://developers.facebook.com/docs/graph-api/using-graph-api/

You may downgrade to v3.0.1 to continue use. https://github.com/facebookincubator/Facebook-For-OpenCart/tags
