Can't remove ssl certificate

[Giannis_Maris]

I tried to remove the ssl certificate but although I have removed it from the IP I'm getting an error that it is still assigned to it. The solution in http://kb.odin.com/en/119514 didn't work cause the Certificate field is grey out in my case.

Did you probably secure the Plesk Panel with the certificate you would like to remove?
