BuddyPress.org

Hi, new to the forums and relatively new two Buddypress (have been using on this installation for around 2 months). I’m running into a problem with the friend request confirmation link — when logged out of Buddypress and following the link from email, only a blank page displays (even no code on “View Source”). It attempts to the following (badly formed) URL: http://pvp-live.com/wp-login.php?redirect_to=http%3A%2F%2Fpvp-live.com%2Fmembers%2Fchestersrp%2Ffriends%2Frequests%2F&action=bpnoaccess

Could this be a redirect issue? I have it set to pretty permalinks with mod_rewrite turned on…
.htaccess looks like this:

# BEGIN s2Member GZIP exclusions
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /test/
RewriteCond %{QUERY_STRING} (^|\?|&)s2member_file_download\=.+ [OR]
RewriteCond %{QUERY_STRING} (^|\?|&)no-gzip\=1
RewriteRule .* – [E=no-gzip:1]
</IfModule>
# END s2Member GZIP exclusions

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Running WP 3.5.1, BP 1.7 — am hesitant to upgrade as I have a bbPress install on this site where I’ve hacked core quite a bit, sadly.

Any thoughts greatly appreciated, thanks in advance.
