A customer was confused by this error message showing on his board: "Due to the configuration for this particular board, you'll have to use the full dialog to create a new issue. Learn more"

Apparently this displays if there are no projects or issue types detected, which is most likely due to the board's filter filtering them out.

The Learn more links to a general page on Configuring boards, but I think we should be more specific in the error message. Suggested text:
"You will need to use the full dialog to create a new issue, as your board's filter is excluding all projects and/or issue types."
