I used to initiate WordPress in my cronjobs by calling something like:
$file = dirname(__FILE__);
$file = substr($file,0,stripos($file,"wp-content"));
require($file."/wp-load.php");
But this isn't working anymore. If I use a test script in the same directory, for example:
require($file."/testscript.php");
It executes without a problem. I also have no problem running the script directly. It's only when it's run from the cronjob.
There are no errors being thrown to indicate a permission or path problem.
So what's happening? Is wp-load.php actively failing due to being called from a cronjob?
I was able to trace the issue back to the way I was handling WP login authentication during the init action hook. So, wasn't WordPress' or cronjob's fault.
