Server connect form validation error required keeps coming

Hey all,

All of a sudden two forms, that I haven’t touched recently have stopped working.

One presents a weird output, too, not the usual error of the server connect:

{"form":{"rec_id[agency_id][inputPositionTitle][inputPositionLocation][inputIndustry][input_placementDate][inputReviewTitle][inputReviewerFname][inputReviewerLname][inputReviewerLocation][inputReviewerCompanyName][inputReviewerEmail][selectReviewerType]":"This field is required."}}

Seems to be something related to form validation. (I’ve checked, removed, triple checked etc.) and nothing is incorrectly setup - and even on a form with no validations anymore - I get this.

Wondered if anyone else has experienced this?
