Related posts not showing up anymore

I love the new related posts feature and it’s been working great, until today. I tried updating to latest version of Jetpack to see if it would fix, but to no avail.

I see I’m getting this error under the related posts settings: “Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘vaultpress_jetpack_more_info_connected’ was given in /*****/****/public_html/wp-includes/plugin.php on line 470”

This feature has really helped up my pageviews so I need it up and working again. How can I fix this? I haven’t done anything new to my site in awhile so I’m mystified.

My site: smellslikeinfinitesadness.com

Thanks!

Michael
