SymptomsParallels Plesk Panel (PP) is installed within Virtuozzo CT and is accessed through VZPP (offline_management is enabled for the CT and https://server.tld:8443 redirects to https://server.tld:8443/vz/cp/psa/frameset). After logging in to VZCP and accessing any or a specific PP page, the following error is shown:
Service is not available now, probably your Plesk is misconfigured.
Contact Your provider for details.
CauseThis message is reported by VZPP for any error returned by the PP server and does not indicate what the actual error is.
ResolutionMake sure that the PP service "httpsd" is running in the CT:
# ps -ax | grep httpsd
To see the detailed error report, you need to enable the following options in /usr/local/psa/admin/conf/php.ini and restart PP:
display_errors = On
log_errors = On
Then log in to PP, not through VZCP, but directly at http://server.tld:8880. Go to the problem page and check for exact error reported by PP, or check error messages in the PP log file PRODUCT_ROOT_D/admin/logs/httpsd_error_log.
