[SOLVED] Weird Validation Message

When a user enters their username or email address on the registration or reset forms, CB validates that and returns a message. Recently those error messages have started showing up like this: {"valid":true,"message":"CK12313 is available to be registered."}



Can you help me diagnose why this is happening?

Only reason for that is something is outputting during the ajax response breaking the expected json response. Disable 3rd party Joomla system plugins 1 by 1 until it goes away. If it doesn't repeat with non-core CB plugins 1 by 1.

EDIT: It ended up being "System - Notification Message Bar"

Thank you for your help. You guys are awesome! I have not seen so many fantastic updates from a developer in a long time.
