XF 2.1 Receiving Error "Please enter a value using 30 characters or fewer." while creating a new Node

Hello,

I am receiving the error "Please enter a value using 30 characters or fewer." while creating a new Node

How can I debug which setting or add-on is causing the problem?

Thanks

Disable all add-ons, then enable them one-by-one until you find the one that's causing the issue.
