I did get a script error on one of the links for MicroLogix and I would blame it on the controller itself since this is what Google search shows:
"You can access the MicroLogix 1100 Web Server only with Internet Explorer 6, 7, or 8. Internet Explorer 9 or above are not supported because of JavaScript incompatibility. To access data view pages, the browser requires Javascript support."
So, check your controller requirements.
