I tried to install a already existing certificate from GoDaddy on a website in ISPConfig3. I first enabled the SSL checkbox, then copy/pasted the certificate in the SSL tab.
After I did this, apache crashed, and could not start. I'll admit I panicked a bit, but further on I navigated to /var/www/example.com/ssl, and deleted the certificates. I tried to restart apache, but then it could not find the certificates, and would not start (obviously). I went in /etc/apache2/sites-enabled/100-example.com vhost, and removed the certificate paths from:
# SSLEngine on
I then tried restarting apache, but now I'm getting this error message in apache:
[Fri Apr 19 07:57:49 2013] [error] Server should be SSL-aware but has no certificate configured [Hint: SSLCertificateFile] ((null):0)
Any suggestions? Thanks!
