File Upload rejects jpg extension

Help!  My form worked fine in testing now I get an invalid extension error when someone tries to upload a jpg file

Hello.

I believe that I see the issue. On the Extensions entry of each of your Upload Fields, it appears that you have added an accidental space before the jpg extension, so the extension is interpreted as ". jpg" instead of ".jpg". Please try changing it for every one of your Upload Fields so have only a single space.

The entry should be only:

pdf, doc, docx, xls, xlsx, csv, txt, rtf, jpg, jpeg, png, gif

Please let us know if removing that one excess blank space character from your Upload fields' allowed Extensions fixes the issue.

Thanks, that was the problem.
