 * Hey there bonkerz. This happened to me after updating to 2.1… I feel like I’ve
   had to fix this before, even though the changelog states that this issue was 
   fixed in 2.0.
 * Here’s how you can fix it:
 * Open the file **bsk-gfbl.js** located in **/wp-content/plugins/bsk-gravityforms-
   blacklist/js/**
 * Line 12 should look like this:
    `$(".bsk-pdfm-selector-pdfs-dropdown").live("
   change", function(){`
 * Simply change “.live” to “.on” like this:
    `$(".bsk-pdfm-selector-pdfs-dropdown").
   on("change", function(){`
 * Save the file and you should be good to go.

 * Thanks for your help about this plugin. The error has been fixed from version
   2.2 and you may upgrade to the new version now.
