HTML Embed Issues

Hello!

I recently moved my blog from one server to another, and everything worked fine on my old server, but I am having issues on the new one.

I can’t embed YouTube videos, the code disappears when I save the post!

The code tags don’t work, I used to have buttons for people to grab in blog posts, but now they just appear as images, as if the code tags weren’t there at all.

I’m not sure if some setting got changed or is different, but even logged in as editor/admin/super admin I can’t get the codes to show as codes or the videos to embed.

Any idea what is causing this? Thanks!
