 We are running Wordpress using multiuser with Buddypress. Users are
 getting the 404 error after they click the save button in their settings.

 I'm opening this ticket to report the source of the problem.

 Wordpress 3.x
 Buddypress 1.5
 Windows 2008 R2 (IIS 7.5)

 Themes installed are all Buddypress compatible and all themes seem to be
 affected.
 All option pages are affected.
 Settings are updated when the user returns to the page - despite the
 error. A screen shot of the error can be seen at
 http://blogs.cnc.bc.ca/gagel/?attachment_id=38

 The source of the problem appears to be in the wp_get_referer() function
 on line 164 in options.php. With the variables passed to the function it
 should redirect the user to the page they just submitted when they updated
 options. Instead they get the 404 error.

 The page they're redirected to appears to be the absolute path of the
 submitted page appended to the absolute path again (minus the domain). So
 it looks like this:
 userblog/wp-admin/userblog/wp-admin/options-general.php?settings-
 updated=true

 When I switch out the wp_get_referrer() function with the variable
 $parent_page then the redirect worked as expected.

 I'm uncertain about leaving it like this as my change may have introduced
 issues elsewhere...
