I do have a web part page in my communication site. I did activated the publishing feature of both site collection and site feature. But, I am not able to see content editor web part. Users want to add scripts
Here is the attached:
you are in a Modern site (Communication site).
By default, scripting is disabled, that why this kind of web part are not available. To get this webpart you need to allow custom script on the site.
To do that 2 solution,
use PowerShell to allow script only on one site collecction with the cmdlets :
Set-SPOsite -DenyAddAndCustomizePages 0
To do that, you must havee GLobal admin persmission for SharePoint
