Error on Login to Coldfusion Administrator

Hi,

Recently I have started receiving the following error when I try to log in to CF Administrator, or generally use the CFApplication tag:

class "coldfusion.util.URLDecoder"'s signer information does not match signer information of other classes in the same package

It may have started when I installed the recent update / or when a server certificate expired. However, a restore from backup has not fixed it.

I think some security problem may have occured with the various java classes being used by CF, but what that means in reality I dont know. Its also related to sessionmanagement and it being turned on.

Here is a log entry:

"Error","jrpp-1","11/08/06","21:52:01","SoBS","class ""coldfusion.util.URLDecoder""'s signer information does not match signer information of other classes in the same package The specific sequence of files included or processed is: D:\Intranet\index.cfm, line: 117 "
