Well, yes, its impossible to buy a signed SSL certificate from a trusted CA bellow 2048 bits since long time ago...
On the other note, I have tried everyting, but I get the same errors.
When adding to Snome One, in the certificate field, I entered the Web Server certificate, empty line, then the Root CA from Geotrust, empty line, then the Intermediary CA from Geotrust.
In the private key section, i enter the private key.
I add it as a server certificate chain+private key.
I see the domain name in the certificate list.
But when I try to acess the admin web via https I get the errors...
