Are you sure went through all of the steps on the link I posted? (What exactly do you mean you’ve tried all the fixes?)
Is there any way to indicate if JQ is loaded and working with firebug? This was working fine before I moved it to wordpress.
Step 4 kindof clears that up.
Once that has worked, add the plugin beneath the jQuery library. Make extra sure the plugin file exists and it is linking to the right place. It should then work.
