I'm seeing that it's throwing a notice because it's using a deprecated function
Notice: WP_Query was called with an argument that is deprecated since version 3.1! "caller_get_posts" is deprecated. Use "ignore_sticky_posts" instead. in /Users/jonathandingman/Websites/massive.dev/public_html/wp-includes/functions.php on line 2712
Any chance of getting this plugin updated to use modernized code?
