I had a cert specifically for my mail server but then I upgraded to a wildcard for the domain so I can use it for multiple servers. 

I wanted to replace the cert so I pasted in the CSR I used in and then the bundle ... what happened was the CSR field went blank,  it showed my cert, its issuer and all the other information except the domain it worked for.  It should have showen *.domain.com  but it was blank. 

I tried to put in the old CSR and old CERT just to revert back until I figured out what I was doing wrong but it wouldn't accept that either.  The CSR remains blank even have a restart of the server etc. 

So I really should only need 2 things for this certificate to work -  the CSR and the CERT (bundle in my base).  I even tried to manually enter it into the /usr/local/surgemail/ssl/surge_cert.pem without luck. 

Bug or am I doing something wrong?  This has always worked in the past.
