Can't edit posts after adding the <!--more--> tag

I added the tag ( ) to a couple of my posts and now when I try to edit them they just show blank, like it’s a new post.

@support please help.

Hmm, if you switch to the “Plain Editor” does your post show up?

There is an issue with the Rich Text Editor where sometimes HTML can cause it not to show up entirely – but that shouldn’t happen with the <!--more--> tag.

It does show up on the Plain Editor.
