[Plugin: jQuery Accordion Menu] multiple 404 errors being logged

Hi,

I’ve been receiving hundreds of 404 error logs per 24 hour period from different IP addresses for a javascript call for the vertical accordion menu plugin: ​http://englishlc.com/wp-content​/plugins​/jquery-vertical-accordion-menu​/js​/jquery.cookie.js?ver=3.5.1

The plugin has been installed for over a year, and continues to function as normal. What could be the reason for this?
