CA certificate was removed using Plesk GUI:
Plesk > domains > example.com > Websites & Domains > secure your site > certificate_name > press remove
After that apache is not able to start:
# service httpd start Starting httpd: Syntax error on line 56 of /var/www/vhosts/example.com/conf/14410094520.45554000_httpd.include: SSLCACertificateFile: file '/usr/local/psa/var/certificates/cert-Eb0hQK' does not exist or is empty
This issue has been considered as software issue #PPPM-3230 and was fixed in Plesk 12.0.18 version.
Add new certificate parts (server and\or CA) either as files or as text:
Plesk > domains > example.com > Websites & Domains > secure your site > certificate_name
Plesk will ask if you want to replace existing certificate - click yes and restart apache.
If it doesn't help:
Disable SSL support for domain:
Plesk > domains > example.com > Websites & Domains > Hosting Settings
Restart apache and reconfigure domain:
# service httpd start #/usr/local/psa/admin/sbin/httpdmng --reconfigure-domain example.com
- Enable SSL support and upload SSL certificate to the site.
