When
an end user tries to create an individual site collection on their personal My
Site page by clicking the My Content link for the first time, he might
encounter this error message.
There has been an error creating the personal site. Contact your
site administrator for more information
This
error can occur when the SharePoint administrator does not use a wildcard
inclusion managed path to configure the My Site Settings for the User Profile
service application connected to the Web application that hosts My Sites.
If
you create the My Site host site collection that is deeper than the root path,
the site collection must use an explicit inclusion managed path.
Please
try these steps to resolve this error message:
1. Central Administartion
-Click
Application Management.
-In
the Service Applications section, click Manage service applications.
-On
the Manage Service Applications page, click the User Profile service
application that is associated with the Web application that hosts My Sites,
and then, in the Operations section of the ribbon, click Manage.
-On
the Manage Profile Service page, in the My Site Settings section, click Setup
My Sites.
-On
the Manage Profile Service page, in the Personal Site Location section, verify
that the value in the Location box is a wildcard inclusion managed path defined
on the Web application that hosts My Sites. If not, create a new wildcard
inclusion managed path for the Web application, and then use it as the value in
the Location box
2. Self-Service site creation:
-Open
Central Administration
-Under
Application Security select Self-Service site management
-Select
the Web Application that is hosting My Sites
