I am also receiving the same problem. I reported the site as down to my host and they identified this plugin as the reason for the error.
The error message presented in IE is:
The website is too busy to show the webpage ( HTTP 408/HTTP 409)
This error (HTTP 408 Request Timeout or HTTP 409 Conflict) means that the server took too long to display the page or there were too many people requesting the same webpage.
Disabling the plugin allows the website to load and run without issue
