Now that I’ve been able to “successfully activate” BP on a sub site (thank you @djpaul) this is my next hurdle. There is no BP toolbar in the WP dashboard. I have a multisite installation running on WP 3.4.1 with BP 1.6. (Yes, I’m a newbie when it comes to most code, WP and BP.) If it matters at all, I’m on OS X 10.7.4 using Safari 6.0.
I hope any solution you provide can help both @nlmdep and myself.
THANK YOU! After setting the BP_ROOT_BLOG in wp-config.php to the ID of the subsite, BP was “successfully activated.” Except that when I try to run the installation wizard it tells me I “do not have sufficient permissions to access the page.” I am listed as admin for the subsite … There may be a larger issue with WP install or conflict with a plugin?
