I have an external script that needs to load up WordPress in order to have access to WordPress functionality.
In the past I have successfully done this by including wp-load.php. However, when using MultiSite, this does not work. It appears to be logged as a bug here.
Does anyone have any work arounds or solutions?
I posted a way to accomplish this here. Essentially, my suggestion is to create a sort of API for your WP installation to maintain orthogonality between your systems.
