    Is there a size limit for uploads in a form?

    Asked by rieglej on October 13, 2016 at 01:28 PM

    I'm having a problem with one of my forms. 


    The student is trying to attach three pdfs - 3.68mb, 3.74mb, and 2.32mb. If all three are uploaded then the form crashes. And I get the error message attached. File size limit is set to 10240KB.

    I can do any two out of three, but over that after I hit submit, I get the error: Form not found: Form Id is missing or irregular


    Is there some kind of limit I'm missing? My account shows: 201.49MB of 1TB used
