SharePoint Online Modern Site Solution Link Missing Under Web Designer Galleries & Content Editor

# How to Enable Custom Script for SharePoint Online Modern Site

If you create a SharePoint On-Premise site and go to its Site Settings page, the "Web Designer Galleries" section appears like this:

Classic SharePoint Option

But when you create a new SharePoint Online Modern Site, the “Web Designer Galleries” section shows very limited options:

Modern SharePoint Option

If you want your Modern Site to show all options similar to an On-Premise site, you can enable them using PowerShell. Follow the steps given below:

1. Open PowerShell: First, open “Windows PowerShell ISE” by selecting Run as Administrator.

2. Set Execution Policy: If you are using PowerShell for the first time, allow permission to run commands:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted

After this, click on “Yes to All”.

3. Install SharePoint Module: Install the module needed to communicate with SharePoint Online:

Install-Module -Name Microsoft.Online.SharePoint.PowerShell

4. Credentials Setup: Create a variable to store admin credentials:

$cred = Get-Credential

Enter your SharePoint Online Admin username and password in the pop-up that appears.

5. Connect to Service: Now connect to the SharePoint Admin Center:

Connect-SPOService -Url "https://yourtenant-admin.sharepoint.com" -Credential $cred

6. Enable Custom Script: Run the final command to enable all hidden options:

Set-SPOSite "https://yourtenant.sharepoint.com/sites/yoursite" -DenyAddAndCustomizePages 0

Note: -DenyAddAndCustomizePages 0 means Custom Scripting is ON. To disable it again, replace 0 with 1.

7. Verify: Refresh the Site Settings page — you will now see all the additional options.

8. Disconnect: After completing the task, disconnecting the service is a good practice:

Disconnect-SPOService
