Every contribution I try to make on the Live, Front End results in the following error:

Sorry. A non-recoverable error has occurred.
This contribution has already been submitted. Click here if you want to make another contribution.
Return to home page.

Test Contributions in the Admin Back End process just fine.

I tried setting both the live and test URL's to the live URL, and still same issue.  I had read a forum suggesting to delete the test contributions, they have been removed, and still same issue.  I tried removing HASH, still same issue.

Anyone else seen this error before?  Any help would be greatly appreciated.
