Error in activating Publishing feature in SharePoint Online

Question

I am receiving an error message saying "A duplicate content type name "Display Template" was found." when trying to activate publishing feature at SharePoint online site collection.

this site collection was initially created as a team site.

pls share your thoughts.

Answer 1

Use SharePoint online Management Shell to activate the feature.

To identify the exact feature ID, we need to browse the manage site features ro site collection feature page and inspect the specific feature button in browser developer tools using F12 and grab the unique GUID.

use that in the powershell with example as shown below:

Import-Module Microsoft.Online.SharePoint.Powershell
$siteurl="https://sitecollectionurl.sharepoint.com/sites/testsite"

[Microsoft.SharePoint.Client.ClientContext]$clientContext = New-Object Microsoft.SharePoint.Client.ClientContext($siteurl)   

$username="loginname@domain.com"
$secure_string_pwd = convertto-securestring "yourpassword" -asplaintext -force

$clientContext.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $secure_string_pwd)


$site = $clientContext.Site;    
$featureguid = new-object System.Guid "f6924d36-2fa8-4f0b-b16d-06b7250180fa"     
$site.Features.Add($featureguid, $true, [Microsoft.SharePoint.Client.FeatureDefinitionScope]::None);     
$clientContext.ExecuteQuery();
