Re: Code Listing using the wrong style
You need to go to the page http://lockbox.seanbdurkin.id.au/tiki-admin.php?page=textarea . This page is linked to from the "Editing and Plugins" icon in the top row of icons, as shown in your screenshot. I think the text links shown at the bottom of the screenshot are meant to be quick-links or supplementary or something but this relationship isn't clear, so this should probably be improved/fixed.
