Could you explain that a bit more? I'm good with PHP, but never seen this kind of problem before. Does this mean global.php has to be modified to work from functions? Hopefully not, as I suspect it's a big task.

Likely should be another thread, but I also get identical the error:
Fatal error: Call to a member function query_read_slave() on a non-object in /mypath/includes/functions.php on line 3189

This error has only started to appear over the last few weeks (with v3.8.3), and I've not made any code changes, nor have I seen this error in the last year or so (I carefully track PHP errors).

Similar to jonbach's function, I use a function to handle creating threads:

function newThread() {
        ... initialization stuff

	chdir($forumDir);
	require_once('./global.php');
	require_once(DIR . '/includes/functions_databuild.php'); // for new thread

        ... forum actions

	chdir($curDir);
}

This has been working perfectly for quite a while (many vBulletin versions over a year or so), so it's also puzzling why it's worked before and lately generates errors.
