Sometimes you will need to activate a feature to use the web part on a site. In this article, I’ll show you how to activate a feature in Site Collection Features with just a few clicks.

Open SharePoint PowerShell and run it as administrator. Then run this script:

Enable-SPFeature
-Identity FeatureName -url <URL>

For example:

Enable-SPFeature
-Identity “Bamboo.CalendarViewExtended”-url http://vschauo16

Now, refresh your site to see the feature activated as expected.
