Have you changed admin templates or edited the template's index file?

No, at a point now where I am going to copy the live environment back to the development area and start over again.

You could do that, but I think it's likely that some file or files have become corrupted somehow.

Back up the site if you can, and then overwrite the entire /administrator folder with one from the Joomla install package of the version you're running.

THEN, if it's not version 2.5.8, upgrade to that.
