ndwiens on "[Plugin: Jetpack by WordPress.com] Can't use "Sharing" component Error code: -32601"

For the past few months we've tried setting up social sharing from Jetpack on our WordPress site running Divi 2.6.4.1. We're able to set up the WordPress.com connector, but when I try to connect Twitter or Facebook I get error code -32601, which we can't find any record of online.
We've gone through several updates on Jetpack to no avail, any help would be greatly appreciated. The site is: frenchhour.com.
