I'm running Plesk 8.6.0:

I have an SSL cert installed through Plesk's admin interface. But I have a bit of an issue: When I enabled SSL for the site, and selected my cert, then restart httpd, Plesk defaults to using my self-signed default certificate.

Conversely, when I disable SSL support for the domain, all of a sudden Plesk is using my new SSL certificate. Unfortunately, when I try to view any folder on the site (mydomain.tld/folder) I'm simply met with a 404 (with files placed both in httpdocs and httpsdocs). I switch SSL support back on, and Plesk defaults back to the default self-signed cert and I can then view the folders that were not previously accessible.

Any ideas?

One further note: I tried following http://kb.parallels.com/en/939 . Once I tried to restart httpd with the edited ssl.conf file, I received an httpd could not start error. I restored the original ssl.conf file, and still received the could not start error. So as of now, I am running without an ssl.conf file.

The following is the error I receive when I attempt to reintroduce ssl.conf:
