Okay, I’m getting closer on my own.
I see in http://www.wpdownloadmanager.com/doc/settings/basic-settings/ that there should be on option to “Show Only Login Button Instead of Login Required Message”, but I don’t have that option/link showing on my settings page.
I tried using this code but it redirects to a package page instead of doing a direct download.
<div class=”w3eden”><i class=”fa fa-lock”></i> Login to Download</div>
Note that I borrowed this template from the free version of Download Manager. I want my template to function in the Pro version the same way it does in the free version.
