PayPal checkout error

In testing there is no problem with PP_confirm checkout but now I uploaded the site and after logging in to PayPal and hit continue button and then the following error:


Warning: mysql_pconnect() [function.mysql-pconnect]: Access denied for user 'ronald50_rBiz'@'localhost' (using password: YES) in C:\wamp\www\reunion\connections\dbc.php on line 17

Fatal error: Access denied for user 'ronald50_rBiz'@'localhost' (using password: YES) in C:\wamp\www\reunion\connections\dbc.php on line 17

I inserted the API info from PayPal for live site. The connection info works when, for example,
I access my questions and answers from my database so I don't know any other password location that could be causing this problem
Thanks

it looks like you are testing on your local wamp server and the conndection file at connections\dbc.php is set to use the username for the remote server.

the default user created by wamp is named "root", when testing locally, your connection file will need to use the root user and password.

Sorry, I wasn't clear. I'm finished testing and uploaded my site to the web. To go from PayPal sandbox to "live", I changed the password and signature in the PP_confirm page to live API credentials. So it's on the web where PP_confirm doesn't work anymore. The web connection file has the remote username and password.
Thanks

send a link where i can see the problem

I included a zip file to show PP_Confirm page and my connection file
Thanks

send a link where i can see the problem

Sorry. The link is pp_confirm.php What I discovered is that if I use my pp_confirm.php , everything shows up correct. However when I click submit the transaction, I get pp_checkout_failure.php

well, yes, the localhost address:
pp_confirm.php

is using your local wamp server for testing, like i said in my previous reply, you are running the pages from your local server and the database connection is set to connect top the remote server.

you need to use the live server address for doing the transaction.

to troubleshoot why the transaction is failing, add the following code to the pp_checkout_failure.php page just before the closing </body> tag:

<?php

     @session_start();

     echo "<p>Express Authorize: <br />"; 

     echo "Full Request: ".(isset($_SESSION["ECO_Auth_Request"])?htmlentities($_SESSION["ECO_Auth_Request"]):"n/a")."<br />"; 

     echo "Full Response: ".(isset($_SESSION["ECO_Auth_Result"])?htmlentities($_SESSION["ECO_Auth_Result"]):"n/a")."<br /></p>"; 

     echo "<p>Express Process: <br />"; 

     echo "Full Request: ".(isset($_SESSION["ECO_Process_Request"])?htmlentities($_SESSION["ECO_Process_Request"]):"n/a")."<br />"; 

     echo "Full Response: ".(isset($_SESSION["ECO_Process_Result"])?htmlentities($_SESSION["ECO_Process_Result"]):"n/a")."<br /></p>"; 



?>

this will write the full request being sent to paypal and the response coming back to help determine the cause of the failure.

NOTE: the full request and full response will contain sensitive information that should be removed before posting here,

OK I don't understand. I uploaded my site to the internet and the connection file has only the web username and password. The host name is localhost. Where am I suppose to change something to start using internet settings so PayPal works?

in your previous message you say:

  Sorry. The link is pp_confirm.php What I discovered is that if I use my pp_confirm.php , everything shows up correct. However when I click submit the transaction, I get pp_checkout_failure.php  

the address:
pp_confirm.php

is using your local testing server, this isn't working because the settings are for the remote server.

the address:
pp_confirm.php


is using the remote server which is working except that you are getting the payment failure page.

you need to be using the live server address for testing not the localhost address

on the payment failure page add the code that i provided in my previous response so that we can troubleshoot why the transaction is not working, until I know the full request and response info, i wont be able to troubleshoot the transaction failure.
