Hi Simon, I would suggest you follow the advice you’ve received from the theme developer in addition to the MySQL settings tweaks that I suggested previously. The server sounds powerful enough to cope with your requirements.

Best wishes, Christian

Hi Simon,

There seem to be two issues here. Am I right in thinking that both of the following are true:

1. BuddyPress pages are blank
2. There’s a PHP warning on some pages

Let’s take these in turn…

1) The blank BuddyPress pages are unlikely to be caused by the PHP Warning, since the scripts would continue to to execute. There must be a more severe error in the logs that causes script execution to halt completely. If you don’t have access to the server logs, you can get WordPress to create its own error log by adding the following to your ‘wp-config.php’ file:

define('WP_DEBUG', true);
define('WP_DEBUG_DISPLAY', false);
define('WP_DEBUG_LOG', true);

This should cause a file called ‘debug.log’ to be created inside the folder ‘wp-content’ with the details of the error when you visit a BuddyPress page.

2) It’s not clear to me on which page(s) the PHP warning appears. If you want to investigate this properly, then some debugging code will help. Keep the above constants set in ‘wp-config.php’ and add the following just before line 65 in /home/xxxxxx/public_html/members/wp-includes/load.php

if ( ! is_array( $_SERVER ) ) {
	error_log( print_r( array(
		'method' => __METHOD__,
		'SERVER' => $_SERVER,
		'backtrace' => wp_debug_backtrace_summary(),
	), true ) );
}

When you see the warning, look in ‘debug.log’ to see the results of the logging. What strikes me as particularly strange is that the $_SERVER variable is not an array – this array is normally built automatically by PHP to provide server and execution environment information. To find out if this array is usually populated, create a file called ‘phpinfo.php’ in /home/xxxxxx/public_html/members/ that contains just the following:

<?php phpinfo(32); ?>

You will then need to visit the URL that corresponds to this file. This will show you all your PHP variables. You should have variables such as _SERVER["HTTP_HOST"], _SERVER["PATH"] and so on. Do you see any of these? If you do, then we need to dig deeper into why $_SERVER is not what’s expected on your site. You can delete ‘phpinfo.php’ when you’ve verified this. Also, probably not wise to post the results of phpinfo() here.

Cheers, Christian
