I'm not seeing the directory "djangotest" in your directory list. Did you change the name after you unzipped my zip?

If this is an addon domain problem then post your issue here:

If this is a Parked domain problem then post your username, default domain, and parked domain.
That error has nothing to do with php working on your site. To check for php, create a page and call it "info.php" and add this code to it:
<?php
phpinfo();
?>
I'll go ahead and escalate this to djbob so you can install wordpress from Fantastico.
I just got this working with djbob's help yesterday:

Unzip this in your public_html directory and it will create a directory called 'djangotest' with all of the test files. Just make sure you change the paths.
