Upload file function not working on intake form

Hi, as part of my intake form questions while scheduling an appointment, I added a file upload option for customers to upload their resume. However, when I try booking a test appointment using incognito mode on Chrome, clicking the "Choose File" button does nothing. Only a small message appears that says "javascript:doFileUpload('13286556')" in the bottom left of my browser.

Any fix for this?

I'm having a similar issue, but my file upload page no longer has any options at all.  It had been set up to include a form for contact info and description of client's needs, and a button to click to upload a file.  Suddenly today there's nothing except a blurb about other ways to get their files to us.  Any idea how to fix this?
