Signed Certificate Error: "Uploaded file isn't a certificate"

Hi, 

Looking for help to troubleshoot a Certificate Signing Upload.

We've followed the usual process to generate a signing request and our digital partner has sent back the signed certificate. I have three files: the certificate (File type: Security Certifcate), a Cert-CA (File type: PEM) and a Cert-full (File Type: PEM). They are adament that the certifcate is signed correctly, but all three files result in the same error message. "Uploaded file isn't a certificate"

In previous years, we've simply uploaded the secuirty certifcate and it's worked straight away.

Any ideas on how I can troubleshoot this? Salesforce support can't help as Premier Support is required and the digital partner are adament that the certificate is correct.

Cheers!
Lauren

Many thanks!

I had already check this - the certifcate does indeed have Begin and End tags. I opened the certificate in notepad and checked that.

Any other ideas?
