Malformed certificate on Chrome on XP

I have recently setup a SSL certificate for a website on a new server.
I combined the certificates into one file in order to suppress any warnings.

On a Windows XP machine with Google Chrome I am getting a ‘malformed certificate’ error (see image above).

How is this resolved? If a different SHA version is used will it resolve the issue or could this be something else?

Thanks for your help


What’s the server software?
That might help narrow down the issue.

And how did you combine the certificates?
