I am having exactly the same problem with my blog colleague, who is “Editor” on my blog. But it’s not just embedded media, it’s all paragraph codes that disappear when he opens a post for editing. <br />
‘s and <p>
‘s are all gone when he opens the post, whether it was created by him or by me, whether it’s published or as a draft. It happened in wordpress.com, and still happens now we moved to worpress.org.
We’re both on PCs using the latest FireFox, and he doesn’t use the Visual editor, only the HTML.
This is driving me crazy! Help!!!!!!!
