Resolution
When Sitebuilder is integrated with Plesk, the default working directory in the publishing settings of Sitebuilder is set as /httpdocs/site
It is by design that the file content is stored in /httpdocs/sitebuilder folder to avoid confusing the files generated by Sitebuilder and
the original content of Plesk domain public root folder /httpdocs. To
change the default URL of the sites published with Sitebuilder from www.domain.com/site to www.domain.com please follow the steps below:
1) In the Sitebuilder publishing settings of the domain, change "Web site URL" to http://domain.com and "Working directory" to /httpdocs/.
2) Redefine the order of the domain default pages (the meaning is that default.htm, default.asp pages must be on top) in Plesk accordingly
3) Click on Verify Location option to check the settings.
module data was not showing up, particular any Image Gallery and Forum data
4) Republish the site in Sitebuilder with the new settings. In case of errors, olease rename the /httpdocs/web.config to /httpdocs/web.config.old and try to publish the domain once again.
