An unexpected error has occurred when trying to create an Enterprise Search Center in SharePoint 2010

Issue Description

I tried to create a SharePoint Search Center with site template as Enterprise Search Center within a site collection in SharePoint 2010 and got the below error.

Reason

The SharePoint Server Publishing Infrastructure feature must be activated at the site collection level before creating a site with Enterprise Search Center template.

Resolution

So the next step was to enable the Publishing Infrastructure feature.

1) Go to Site Actions -> Site Settings -> Site collection features -> SharePoint Server Publishing Infrastructure

2) Click on Activate
