There are only two providers that use that code: Twitter and Yahoo.
If you're encountering that error with Twitter, then please follow these simple steps to update your Twitter application:
To fix, please:
* Go to the Twitter Apps Area
* Click into your app
* Go to the 'Settings' Tab
* In the 'Callback URLs' section, add all variations of your domain with 'index.php' at the end. So, for this site, we would add:
http://sourcecoast.com/index.php
http://www.sourcecoast.com/index.php
https://sourcecoast.com/index.php
https://www.sourcecoast.com/index.php
Twitter changed something on their side about 2 months ago that requires this change, so you would have been seeing it since then.
