And most important

HTML Code:
.htaccess Basic Authentication Mode
Your site Site in installed with PHP over CGI? 
This configuration will disable PHP Basic Authentication that is NOT compatible with CGI used in the responsehandler.php to validate Google Checkout messages.
If setted True you MUST configure your .htaccess files here.
1-Yes, My site has an SSL.
2-The credentials are correct... GC works fine, only the coupon code is making an issue.
3- I am not sure where to locate the log folder
4-.htaccess has the following for GC:

#AuthName "Google checkout Basic Authentication"
#AuthType Basic
#AuthUserFile /home/content/98/6507445/html/googlecheckout/.htpasswd
#require valid-user

Any Idea what might be wrong?

thanks!
