File upload w/ cryptic error message blocks submission

Dear All

I have the latest versions of both WordPress and Caldera Forms.

Since recently (I think around the time WP was updated), the file upload feature of one of my forms stopped working.Cryptic messages appear like
Content hash did not match expected.
Missing parameter(s): verify, formId, fieldId, control

More importantly this bug blocks the submission of the entire form. So I am not even notified that someone attempted to upload a file.

I figured it was a bug that would be ironed out but it’s been more than a month and I’d like to know if this bug will be fixed.

Will it go away with the paid version?

Regards

Andy
