[For 1.8] Thank You/Like System v3.3.7 + MyAlerts support

What's the best way to troubleshoot this?
Is there some program that can check the site's code and see what is being loaded?
Looking through every file is going to take a long time.
We are good with php, css and html, but nothing js.
I didn't even know that loading the same js more than once can cause problems.

Thanks mate!
