Trail plan does not have any site families enabled.

A Trial plan is associated with trial sites created through Parallels Plesk Sitebuilder Wizard. This is a plan selected with grey background on page Plans in Parallels Plesk Sitebuilder (General -> Users -> Plans). By default the trial plan is called “Default plan”.

To see the problem select the trial plan and change to page Site Families. The problem occurs if no site family is enabled.


A plan must contain at least one Page Set and Site Family. If Site Family is missing it is recommended that you enable it. Login to Parallels Plesk Sitebuilder as admin and change to the management page of the trial plan at General -> Users -> Plans -> Default Plan.
