Neither answer is correct or answers my question. To the first poster, I said that I am the administrator. WordPress DOES NOT strip out iFrame for admins, just users with lower levels. And it was working before… until Friday.
And to MickeyRoush, I just need to add YouTube and Soundcloud embeds to my posts. And I know you can just put a Youtube URL in there and it’ll automatically embed it, but not with the same customization. Your suggestion would be if it were part of the framework of my site.
So if anyone else has an answer, that would help!
