File Upload Field

I have added a “File” extra field and can upload one file to the field. The file is actually a jpg, as it is a picture of a course certificate. The file uploads fine and displays in the Users>Users Extended section. When I click on the link to the uploaded file, either in the Users extended section or the user profile, I get a new tab displaying: “403 Forbidden Access to this resource on the server is denied!” I am the site admin and the file was uploaded to my own profile.

Can anyone provide guidence on this please?

Thank you

Bruce
