[Chameleon] Blank screen

[Seiple, Timothy E]

When attempting to test the default template, my browser produced a
blank white screen.  The following sequence of PHP errors also appeared
in my Apache error log:

PHP Warning:
[MapServer Error]: msLoadMapContext(): Unable to set units for
projection ',\x0el\x02,\x0el\x02g:4326'\n 
in C:\\Program Files\\Chameleon\\cwc2\\htdocs\\cwc2.php on line 718

PHP Warning:

PHP Fatal error:

I don't really know where to start with this problem.

Thanks in advance, 
Tim
