Parallels Plesk Panel integrated with Parallels Sitebuilder is installed on the server. Any attempt to configure specific domain to use Publish sites with sitebuilder option in Home > Domains > domain.tld > Setup page fails with the following error:
Error: Sitebuilder license error: The limit on the number of SiteBuilder sites is reached
However Sitebuilder license has enough number of sites which can be created.
Most likely this domain is configured as Host in Sitebuilder and domain name instead of IP address is used.
- Plan which is assigned to current user (Plesk Client) in Sitebuilder does not have sufficient limit for sites creation.
Please go to Sitebuilder > Server > Hosts > Hostname (in this case it should be the name of issued domain) and ensure that IP address filed contains IP address than DNS name.
- Current plan can be checked in Sitebuilder Admin > Users > User_name/Plesk_Client_name > Plan.
Then it is necessary to go to Sitebuilder Admin > Users > Plans > Plan_name and check Maximum number of regular sites value.
