For one of my domains, I noticed it was stuck as ‘suspended’ but was still functioning. This was due to my server going offline during a Plesk cp backup. There are two ways of fixing this:
If your domain is just that, a domain then run this command as root from your CLI
/usr/local/psa/bin/domain -u <full_domain_name> -status enabled
It should then tell you that it was successful, and hopefully your domain is back to normal. –
SUCCESS: Update of domain ‘example.com’ complete.
For domains that are part of a client, or if a client has been susspended simply run
/usr/local/psa/bin/client -u <login_name> -status enabled
