I went to my download in Download Monitor and I don’t have the option to set Force Download to true. These are the options in the download options box on the right :
Featured download
Mark this download as featured. Used by shortcodes and widgets.
Members only
Only logged in users will be able to access the file via a download link if this is enabled.
Redirect to file
Don’t force download. If the dlm_uploads folder is protected you may need to move your file.
