JetPack Publicize is failing to authorize – The last part of the process throws a 404

The site in question:

http://littleriverband.com

Framework: Pagelines (this framework is usually not an issue for jetpack publicize and may not necessarily factor into the problem here)

Plugin in question:

Publicize: http://littleriverband.com/wp-admin/options-general.php?page=sharing

is not authorizing. After it attempts to do so it throws a 404 – I tried twitter and Facebook – both failed

URLs returned that 404’ed:

http://littleriverband.com/main/wp-admin/options-general.php?page=sharing&action=completed&service=facebook&id=4263985

http://littleriverband.com/main/wp-admin/options-general.php?page=sharing&action=completed&service=twitter&id=4263866

In the end there was no authorization made.
