Bug give_get_current_page_url() $_SERVER["SERVER_NAME"]

[remcotolsma]

The give_get_current_page_url() function is not working correctly on all nginx configurations. I use a name-based virtual hosting environment with nginx:

The value of $_SERVER['SERVER_NAME'] is:

~^((?<subdomain>.*)\.)?(?<domain>[^.]+)\.(?<tld>[^.]+)$

This is causing all kind of issues, I think you should use $_SERVER['HTTP_HOST']:

• https://github.com/WordImpress/Give/blob/1.3.6/includes/misc-functions.php#L190-L217
• https://github.com/WordPress/WordPress/blob/4.4.2/wp-includes/admin-bar.php#L354

$current_url = ( is_ssl() ? 'https://' : 'http://' ) . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

For now i fixed it by adding this to the wp-config.php file:

$_SERVER['SERVER_NAME'] = $_SERVER['HTTP_HOST'];
