BuddyPress.org

I am having this problem on every recent WP/BP install I’ve been working on lately. All responses from ajax with links in it provide the wrong URLs (with extra subdirectories). I set up a basic, default, latest WP 3.3.1 / BP 1.5.3.1. There are no other plugins installed.

When you do a search on:
https://pic.fsu.edu/courses/2012/spring/test/members/
for “admin” the result from ajax gives the following link:
https://pic.fsu.edu/courses/2012/spring/test/members/members/admin/
instead of the proper link:
https://pic.fsu.edu/courses/2012/spring/test/members/admin/
which is the proper link given during a normal page load of the members page.

This makes me think this is some kind of server configuration. This is my .htaccess, just the default stuff. Tell me if I can provide any additional information!
`# BEGIN WordPress

RewriteEngine On
RewriteBase /courses/2012/spring/test/
RewriteRule ^index.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /courses/2012/spring/test/index.php [L]

# END WordPress`
