Hi, for some reason the scripts are being output twice (I can see it in the page HTML source code). Without seeing what is happening in your WordPress dashboard or theme I can’t say for sure what is happening though. You might try:
1. Have you disabled all other plugins so that only Cookie Law Info is installed, then try it?
2. Have you possibly installed the plugin twice?
3. Is your theme correctly using wp_head() and wp_footer()?
4. Is your theme correctly using wp_enqueue_script()?
5. Are you using a cache plugin (unlikely but maybe that is the cause)?
As this doesn’t happen in the standard WordPress themes (2011, 2012, etc) then it may well be related to your theme or other plugins that you’re using.
Hope that helps
