Sitecore 8.2 Update 4
When I save a WFFM form, I get the error:
Page event definition Field Completed not found, page URL /other/contact-us/general-inquiries
I seem to get it once per field on the form (That makes sense). The event Field Completed does exist in the database.
This is happening in CM and CD. I updated my above statement that it was CD only.
The client does not have Analytics as part of their license, if that is a factor.
