Re-naming Admin creates php errors

[teragram]

In your changes you have created a syntax error which is causing premature output from your site. The warning that you quote above, usually tells you where this output is coming from, but seems to have been chopped off in your post.

I thought that might be the case the first time, which is why I un-installed and re-installed the application. It does not explain why the un-touched configure.php document also generates the same errors.
And I was VERY careful to only change the the /admin/ parts. Using TextWrangler set to document type php showed no syntax errors.
