Hi Jason,
Thanks for taking a look at this. All of my areas are on the site index.php so all are 'Content Location: Home Page'. Here is the full list:
Content Location: Home Page
Content Area: Feature Panel Heading
Content Location: Home Page
Content Area: Feature Panel Text
Content Location: Home Page
Content Area: Footer
Content Location: Home Page
Content Area: Header
Content Location: Home Page
Content Area: Left Frame
Content Location: Home Page
Content Area: Main Content
Content Location: Home Page
Content Area: Right Frame
Content Location: Home Page
Content Area: Sidebar Content
While compiling this list, I have just noticed that while all the Content Area descriptors show correctly in admin/index.php under "Choose the content area you wish to edit below" and in admin/contents_update.php in the 'Currently editing' line, the Content Area title, 'Feature Panel Heading' is curtailed by three characters where it shows in the contents_update.php immediately to the left of the 'Cancel' Button. There it reads, 'Feature Panel Head'.
It is also the first in the list. Perhaps I have exceeded a limit?
Cheers
