Introduction

Enable Scripting Capabilities on modern sites and other sites

Scripting capabilities are not enabled with modern sites (and other sites) by default, and cannot be enabled using the central administrator for modern sites. You can not install ShortPoint SPFx for classic pages on modern sites if scripting capabilities are not enabled. 

• The only way to enable scripting capabilities on modern sites is using PowerShell. 
• You need to have access to your SharePoint Farm Server and you need to be Farm Server Administrator.

(Get-SPSite -Identity "https://your-host/sites/modern-site").DenyPermissionsMask = [Microsoft.SharePoint.SPBasePermissions]::EmptyMask

Replace with your host name

Replace with the path of your modern site

Hit Enter. 

That's it. Now you have scripting capabilities enabled.
