    I can't seem to reproduce the error.

    Your upload field is configured properly. Perhaps it was just a user error. The user might have uploaded an invalid file or file that is not on the file extension list.

    Example, if I am going to browse a txt file on the second file upload field, it shows the warning message as expected.

    Or perhaps it was browser specific, if possible, please ask your users to use updated browsers like firefox or chrome.

    Of course, it works right now because i have used another code. If i use the source code the form won't work. If i use the embed code the for works properly. I was in emergency and i've solved like this. But how can i prevent this error in the next forms? Thanks

    We usually recommend that forms are embedded with iFrame code. This way you can avoid conflicts between your website scripts and JotForm scripts. 

    Inside of this guide you can find how to get iFrame code of your form:
