Hi!
I tried to embed the following url into post editor:
<iframe width="512" height="288" frameborder="0" scrolling="no" src="http://api.dmcloud.net/player/embed/51556c3f06361d781200012c/516fd2a8947399703a00049d?auth=1681647316-0-jei3sj8k-57d33c7b4587f62875e3ed0d85d6a18e"></iframe>
The code is getting removed everytime I click the "save draft" or "preview" button. Embedding youtube videos works. Is dmcloud.net url's not allowed for security purposes?
