I had problems with alias. I get it working in a simpler way:
My drupal is under /var/www/drupal and I want 2 diferent sites at myserver.com/site1 and myserver.com/site2
I only need 2 simple steps:
1.-Create var/www/drupal/sites/myserver.com.site1, copy settings.php inside and setup database conection string at settings.php
2.-Create simbolic links at /var/www
sudo ln -s /var/www/drupal /var/www/site1
sudo ln -s /var/www/drupal /var/www/site2
And nothing else. It works perfectly.

TRY THIS: Type in google ’site:yourdomain.com’

These are the pages of your website that are listed on Google. This gives us a good idea of how your individual listings look for each keyword.

Page title – this is the link text.
Description meta tag – Description text, max of 150 characters. Use word count in Word to check this. Exceeding that the words are cut off and an ellipse (…) is displayed. If a description meta tag is not specified Google will use the first bit of text on the page.

Ideally the title and description will contain specific keywords for that page.

TRY THIS:
Do a search in Google. Notice that if the keyword or keyphrase you used is in the description that it turns bold.

TRY THIS:
Type the following/copy and paste into Google search include the word ’site:’-: site:mediaworks.co.uk
We can see how the experts deal with the page title and description text.

ACTION:
Identify your top website pages, start with only a few 5 at most. We can always tweak other pages later. Choose a keyword or keyphrase. Create page title and description for those pages.

The problem was differing IP address setup on the server.

http://drupal.org/node/541746

I have traced the code to see what the issue is. If I put:

print_r($response);

after

list($response, $http_response_code, $curl_error) = uc_protx_vsp_direct_curl($url, $post);

which is line 535 of the module file I get:

Array
(
[VPSProtocol] => 2.23
[Status] => INVALID
[StatusDetail] => 3058 : The CardHolder field is required.
)

There is indeed no field on the screen for “CardHolder.” If I hard code that field in the code, then it proceeds. I actually realize now that the reason I thought it wasn’t connecting was because I was logging into the SagePay live system and it was configured for the Test system. When I set it for Live, then it indeed connects and I see the error in my SagePay transaction listing: “INVALID – 3058 : The CardHolder field is required.”

I have temporarily set the CardHolder value to be Billing First Name, space, Billing Last Name and now it works fine.

But why do I not have a CardHolder field in the form?
