I am working with SP 2019 on prem. Noticing one of the most weird issues. I have SharePoint server publishing and SharePoint Server publishing infrastructure enabled. Seeing below when editing a classic page, no content/script editor web parts available
I also disabled SP Server publishing feature and reactivated it, still no luck. Under same web application, if I create a brand new site collection, I see all classic web parts, script/content editor everything, no issues. So I think its site collection specific issue.
if any one experienced this before, please shed some light, appreciate the help in advance.
