Just got a new Redhat server running Plesk 7 a few days ago. The first thing I wanted to do is get an SSL certificate for the control panel. I went through the panel and created a CSR. When I went to add my certificate it get the error "Unable to set the private key; Probably the private key format is invalid". I don't understand, Plesk created the private key for me, why wouldn't it accept it?

I should add that this is a FreeSSL cert. Do these not work? If not, I wish someone would tell me and not waste the money.

I upgraded to Plesk reloaded and the freessl certs now work (after having to buy a new cert)
