Internal form submited error

Dear Admin
I submited an Internal form and here is the error:

Oops! looks like there’s a little problem…
Would you like to submit an error report to Infusionsoft?

These error reports help us to provide better, more specific error messages and, in some instances, fix bugs.

Please help me, thank you!

This usually happens when an old link for a form that has been modified hasn’t been updated by re-publishing.
