"Error: The TEXTAREA with id or name set to "edit-enabled" was not found"

Every time I go to the admin/content/mailhandler/add or admin/content/mailhandler/edit/1 I get this message:
"Error: The TEXTAREA with id or name set to "edit-enabled" was not found"
It is an actual message dialog windows, not on the webpage.

It doesn't seem to affect the functionality of the module though. It's workig great after I figured out how to configure the mailbox. So thanks a lot for this module!
