Can't open any of the links of support

Hi all,

I have tried to install and configure “Magento WordPress Integration” plugin and faced a fatal error
“
Fatal error: Cannot redeclare __() (previously declared in D:\xampp\htdocs\wp_mage\wp-includes\l10n.php:146) in D:\xampp\htdocs\mage-wp\app\code\core\Mage\Core\functions.php on line 96
“

I have searched for this error and found that the installation instructions are provided here “http://www.mwi-plugin.com/documentation/installation/”

But I can not open the site as well as “http://www.mwi-plugin.com” too.

Is the site is under construction or something else.

Can any one help me to find the installation instructions please?
