Blank page and 'Failed to Get Basic Authentication Headers' error message

[e1$ki]

Hi,
I posted this last night but can't seem to find it on the Google
Checkout Mod for Zen Cart Support Forum. I have no idea if it got
posted. Forgive me if this is redundant.

I have read the INSTALLATION and README files. Here are a few
paramters of my system.

Zen cart: 1.3.8
PHP: 5.2.8
GC: v1.4.7
Curl is installed. In fact the GC worked on my site previously. (I had
paid someone else to install it.) I had to redo my entire site due to
a hacker and now I'm rebuilding from scratch. So, Google checkout did
work at one point. So, I know that my server is capable.

This is the error: I get to the page with my product. I click on the
button that says "add this to my cart" and it takes me to a blank
screen.

When I visit the responsehandler.php page, I get this message: "Failed
to Get Basic Authentication Headers".
I've been looking through this forum and reading what I can.
I'm reading a little bit about InitSystem and how it uses my
main_page.

I called my ISP to make sure that my site wasn't installed over CGI
and it isn't. These are my parameters

If you have any suggestions to get me past this bump in the road, I

I'll do whatever to make this work.

Thanks again!

Hello,

I am trying to install GC for Zen Cart. I have curl installed and all
that. I paid someone to enable this before on this same website and it
worked before. I had to wipe my whole website clean and I'm trying to
reinstall everything. I don't have a lot of $ to pay to have the
developer install GC again. I'm trying to get it back to working and
I'm hitting a few snags. Here are the parameters that I'm working
with:

Version of ZC: 1.3.8a
PHP Version: 5.2.8 (Zend: 2.2.0)
GC Version: v1.4.7

I have read the READ ME file. I have read the INSTALLATION file. I
have read the documents in this google group under "Pages".

Here is the error:
When I go to [mysite]/googlecheckout/responsehandler.php, I get the
"Failed to Get Basic Authentication Headers" message. When I go to
[mysite/shoppingcart/] and I click on the "add this to my cart", the
page goes blank.

I did as the README file told me "If you get a 'Invalid or not
supported Message', 'Fail to get HTTP Authentication',
or a request for User and Password, go to the next section.
If you get any errors, you must correct all errors before
proceeding.
Refer to the troubleshooting section below or go to the support
forum for help."

I did go through the next section "Setup on Admin UI". Here are my
settings:

Google Checkout Module Version: v1.4.7
Enable GoogleCheckout Module: True
Select Mode of Operation: https://sandbox.google.com/checkout/

Production Merchant ID: *** (merchant id)
Production Merchant Key: *** (merchant key)
Sandbox Merchant ID: *** (sandbox id)
Sandbox Merchant Key: *** (sandbox key)

Sort order of display: 0

I'm not sure what else to do now. If you can help me get this working,
I'd be so appreciative. I've been trying to do this for a few days now
and I'm frustrated but willing to document my problem and take your
suggestions.

Sincerely,
e
