 * I’ll update this if I figure it out, but it happened on both my live site as 
   well as my local development site.

 * Can I ask how you activated GES?
 * What is your WordPress set up like? Is it a multisite install? If so, do you 
   have BuddyPress activated network-wide or just on the main site?

 * My local site is not a multi site…
 * My “live” site, is a multi site.
 * I didn’t try to “network activate” it on the multi site.
 * On the local non multi, I just went to plugins, clicked activate.
 * version info: “Version 3.7.1 | By Deryk Wenaus, boonebgorges, r-a-y”
 * On the local dev copy… this is the raw apache error log pertaining to the error
   I’m getting.

 * Was BuddyPress activated beforehand? If not, I can see why it would throw a fatal
   error.
 * Can you try the following fix?

 * I “just” figured out that BuddyPress is not bbpress… DOH! Sometimes… Sorry, time
   to start reading about BuddyPress and seeing if it fits into what I need. Sorry
   for wasting your time

 * 🙂
 * No worries! Glad you actually found this bug though. It should be fixed in the
   development version.
