"Resource not found" message is displayed instead of a website
After the recent update some users experienced a problem accessing their website - "Resource not found" message was displayed instead.
This is related to an update we have just published which included an urgent security patch from Microsoft.
This problem only affects some computers where people were logged in as administrators before the update. All other users are accessing your website just fine.

Sorry about the inconvenience.
