Wordpress blog integration not working: Error Establishing a Database Connection

Question

I am in the process of integrating wordpress with opencart.

I have succesfully installed wordpress at mydomain.com/wp , it works fine and I can access everything as needed.

I have this, placed just before the start of my opencart header tag on a specific page.

<?php 
/* Short and sweet */
define('WP_USE_THEMES', false);
require('wp/wp-blog-header.php');
?>

and I am receiving an "Error Establishing a Database Connection" error, clearly it is finding wp-blog-header, wordpress at mydomain.com/wp is also working fine and thus connecting to the DB which is why I am confused as to what the problem is. I have a feeling it could be related to this specifically the FILE in wp-config but I am not sure?

if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');

In that header I would define the ABSPATH to point directly to a WP installation, like define('ABSPATH', '/my/webroot/path/wp/'); - hmm? It then should use this defined and do not re-define the ABSPATH after wp-config is included... — shadyyx, Commented Jun 14, 2013 at 15:42
does dirname(FILE) just refer to the current file calling it, or wp-config itself? — Melbourne2991, Commented Jun 14, 2013 at 15:44
dirname(__FILE__) will return the absolute path to the concrete (current) file, that means to Your header file (I do not know whether it is a controller or template file...). — shadyyx, Commented Jun 14, 2013 at 16:03
I tried just writing the absolute path, did nothing. used echo getcwd(); ..none of this makes sense ... Also @shadyyx the __FILE__ is in mysite.com/wp/wp-config.php , not my header which is mysite.com/blog — Melbourne2991, Commented Jun 14, 2013 at 16:06
Did you try using the blog modules available in the market for creating a full-fledged blog in OpenCart? That must be easy and less time consuming. Here is the one if you like to consider that option - fmeaddons.com/opencart/blog-news-articles-module.html — user4104804, Commented Dec 11, 2014 at 7:55

The problem is that the DB_PASSWORD conflicts with one that OpenCart apparently uses this. Changing DB_PASSWORD to DP_WPPASSWD (or a name of your choosing) solves the error. However I now have another error.

Fatal error: Call to a member function main() on a non-object in /xxx/wp/wp-includes/functions.php on line 779
