There is a problem with the page you are trying to reach and it cannot be displayed.

HTTP 500 - Internal server error
Internet Explorer

instead of fixing something related to an obsolete and unsupported browser, tell him to update his browser, it will cost nothing...

Create a new style with no parent - Styles & Templates > Style Manager > Add New Style > no parent - make it selectable by the users. Then have th user with the problem select it and browse the site using this totally default vbulletin style - does he still have the same problem?

A "500 error" usually indicates some sort of sever mis-configuration. Do you have Suhosin or mod_security installed?
