Hi, I’m running into the same error so i will try to explain it in more detail.
What i’m trying to do is to add an ‘file upload field’ to the contact form 7 form. The input button renders correctly and the window to upload a file opens. The form template looks like this.
Your message (optional)
But upon submitting a file the page turns blank and the following error shows up in the console.
As far as i can tell the contact form 7 package tries to set the value of the file input field in the same way it does the normal input fields and causes it to break.
- Add contact-form-7 package to frontity install
- Add contact form 7 plugin to wordpress
- Add shortcode to page (form works)
- Add [file] field to form template (form breaks)
