[Plugin: WP Publication Archive] File not downloading- Blank page is opened.

There is likely something wrong with the way your server is set up.

The plugin itself uses a file (openfile.php) to load the publications as attachments so they’ll download. To prevent people from using this file improperly (i.e. using your site to download/stream remote content), there’s a check at the top of the file to make sure the requested document is being served from your system.

It looks like the fact that you’re using a “www” at the beginning of your domain is what’s breaking things. I can successfully download the files if I remove it. So here are two things you can do to fix the problem:

1) The easy way
After you upload a file, you’ll see the URL in the “Publication” field. Simply remove the www from the address.

So http://www.trinityboyceville.com/wp-content/uploads/2012/01/Test-PDF.pdf becomes http://trinityboyceville.com/wp-content/uploads/2012/01/Test-PDF.pdf

Change that, and it will work.

2) The hard way
Edit /includes/openfile.php and remove these two lines:

if ( strpos( $_GET['file'], (isset($_SERVER['HTTPS']) ? 'https|' : 'http|') . $_SERVER['SERVER_NAME'] ) === false )
	die();

They should be lines 5 and 6 of the file. This is a more permanent fix, but it will open you up to the possibility that your site is used to download/stream remote files … so I recommend using the easy way (#1) for now and I’ll try to work a more permanent fix into the next version.
