First off, I love what you've created. It's simple and effective. However, I have been getting blocked from all my servers (mod_security). I requested the host provide me with the rule triggered and it is a result of this plugin. Bizarre, right?
This is what is triggering my server to block me: GET /wp-content/plugins/column-shortcodes/assets/js/jquery.cookie.js HTTP/1.1
Question though, why is a cookie necessary with this plugin? Can this be removed so I can continue using this plugin or is my only option to trash this?
