Bug
You get a error message at the top and you see comment from the code and the editor does not load.

I would like to see:

1: Hide this comment from the page.

1. are not setting up the wysiwyg but instead stay in wiki mode adding a message and a button to switch
   Collection.

2. Let me know under what situation this problem happens and is it really an issue, that is, why not load the editor!!! This all seems over protection for the user.
