I created the Trac item http://trac.buddypress.org/ticket/1116 for this and copying the issue description here as well.
Setup: WPMU 2.8.4a
BP: 1.1-rc (upgraded from 1.0.3)
Main Blog Theme: Atahualpa 3.4.3 (the blog installed in root)
Buddypress: is installed on a separate blog (i changed BP_ROOT_BLOG in plugins/bp-custom.php) and I use the new theme architecture. Active blog theme: bp-default
I placed the BP core member widget and BP core group widget in my main Atahualpa-themed blog.
Problem #1:
It seems that the style declaration is missing from 1.1-rc (it used to be in 1.0.3 and made these widgets look fine)
.widget_bp_core_members_widget ul#members-list li {
min-height: 60px;
}
Without this style, the 1.1rc widgets look broken (text overlaps with images)
Problem #2:
The Newest/ Active / Popular links in the member and group widget point to <domain>/members (etc) instead of <domain>/<bp_root_blog>/members. When I click on them, the requests time out because of max redirects.
