ERROR: Cannot create table sage_update because it already exists
Ok, so from your post, the table has been written into the database.
In the sage.php file add the following after line 66
echo $sage_update_query;
so it looks like below
Code:
$sage_update_query = "SELECT *
FROM " . sage_update . " ";
echo $sage_update_query;
$ordereds = $db->Execute($sage_update_query);
and post the result
As a side note, you would want to change the lines 230 and 234 to reflect the UK Vat of 20%, byt changing 1.175 to 1.2
