I've created an integration between WordPress and GoToMeeting and embedded a shortcode into a CoursePress post. I've been able to get these steps to work in a single site (non-multisite):
1. Embed shortcode in post which links to http://home_url/index.php?<postvariables>
2. Upon clicking the link, I've added an action on init looking for certain post variables
3. If it finds the correct post variable, it makes a call to GoToMeeting to get the correct URL and then redirects to that URL.
The trouble I'm having is that when I move that to multisite, still using CoursePress, it redirects to
It just displays the site home page and never hooks on init.
Do you all know if there is a difference about how the init hook works in multisite? Or potentially how CoursePress is interacting or redirecting in multisite from a single site?
