Another fatal error:
Fatal error: Call to undefined function: is_user_member_of_blog() in /usr/local/pem/vhosts/233870/webspace/siteapps/87853/htdocs/wp-content/plugins/bp-community-blogs/community_blogs.php on line 104

So sick of the bugs/errors

[Paul Wong-Gibbs]

BP Community Blogs requires WordPress MU/MS, which you aren’t using, which is why you’re getting the error.

[Mark Snyder]

oh no! Is there a way to easily switch?

[r-a-y]

Either deactivate the BP community blogs plugin or if you’re using WordPress 3.0, follow these instructions:
