Hi jhostweb,

although technically the plugin that drives Chameleon can detect requests for pages that start with /administrator, it was a design decision to NOT detect these. The reason for this is that it's far too easy to make actions in Chameleon which could prevent you from even logging in on the administrator side.

I would suggest the use of something like Admin Tools (from Akeeba) where you can protect /administrator by requiring a keyword to be added to the URL. Although that's not exactly what you wanted it achieves the same thing with a good deal of security.

Best regards,
Stephen
