Website root folder - PHP - Wordpress

Question

I've recently set up a VPS server using 123-reg.co.uk

I have a number of sites to transfer to it that use Wordpress as a CMS service.

I 'include' worpress as follows:

require('/blog/wp-blog-header.php');

Which gives me access to predefined wordpress methods such as get_page_by_title( 'home' ) which retrieves the page named 'home'.

Here's the issue, it looks like wordpress relies on an absolute path to further include the files it needs and I'm struggling to get it working.

Further information:

Wordpress is installed in a folder /blog/ It's included as follows:

define('PROJECT_ROOT', getcwd());
include PROJECT_ROOT . "/includes/header1.php";

which calls

include_once PROJECT_ROOT . "/includes/config.php";
require(PROJECT_ROOT .  '/blog/wp-blog-header.php');

The config PHP works fine as does the initial wordpress include.

wp-blog-header.php calls 'require_once( dirname( FILE ) . '/wp-load.php' );'

Which seems to go to '/var/www/vhosts/websitename.co.uk/httpdocs/blog/wp-load.php' which looks right but which causes the site to fail with a generic error (500 internal server error).

Any ideas ?

EDIT: Apache error logs:

Answer 1

假设您在浏览器中访问的页面比安装Wordpress的blog目录高一层，请尝试：

require(dirname(__FILE__) . '/blog/wp-blog-header.php');
