Ajax communication failed

Hi I am setting up a new Zywall USG Flex 500 and have generated a csr and had a new certificate issued for it.  However when I try to import the new certificate I am getting an error.

Ajax communication failed.

In Firefox it justs sits there with 'Import your file...' but the certificate doesnt import.

This happened when I was importing root and intermediate certificates to the Zywall in firefox but after a while I exited and went back in and the certificates were showing in Trusted certificates.

    Hi I have got the certificate to import now, I had stupidly downloaded the wrong certificate.  I still got the Ajax communication failed error but the certificate imported when I had the correct one selected.

    Its not the best that it comes up with that Ajax error at all though.

    Can you share us the certificate which you imported via private message? We’d like to check if we can see the same error message as your.
