Hi,
some time ago I encountered a problem I haven’t been able to nail down until now. A second loop in my WP-theme was suddenly returning wrong posts. I have now realized that reason is found in the class.Apply.php of Download Manager.
add_filter('pre_get_posts', array($this, 'queryTag'));
alters my query as soon as you search for posts with specific tags on the site. I’ve removed the line from the file, and suddenly everything is working again.
I believe Download Manager isn’t meant to alter post queries in templates.
Otherwise it’s an awesome plugin. Thank you for your work.
