Remove all classes after uninstall

Hi,

I’ve installed your plugin but the theme that I decided to use unfortunatelly is incompatible with it, I had to uninstall the plugin.

The issue is that the website still have colorbox plugin references as you can see on the image in this link:

I need your help to clean all the plugin code form my site as it is causing me severall issues.

Thanks
