Corrupted Content Error on newer version

We are working on a site that is not live yet, and had installed WordPress Social Login version 2.1.6 a while back, configured it to work with Facebook, Google, and Twitter, and it worked just fine.

The site is close to going live now, and I updated WordPress to 4.1, and plugins to current versions, moving WordPress Social Login to 2.2.3. With this setup, logins through social media no longer work, and we get taken to a screen which says

“Corrupted Content Error
The page you are trying to view cannot be shown because an error in the data transmission was detected.
Please contact the website owners to inform them of this problem.”

Reverting the plugin back to 2.1.6 got us working again, but I can’t find anything that helps us troubleshoot this error with the plugin.

Any suggestions?

Thanks.
