BuddyPress Member Profiles lost directory or .htaccess

Hi, I have a problem I cannot solve and it is preventing me finishing the site for a presentation

I am running WP 3.1.1 and Buddypress 1.2.8 on Bluehost.com

The web address is http://www.irrilium.com/SecretPlan

Up until last week the build was going well. Sunday I began to get problems with profiles. I can navigate to the members page but on selecting a member or avatar to go to their profile or, when selecting profile from the BP nav bar I got server error 500.

I tried various fixes including renewing the .htaccess file and refreshing Permalinks. This didn’t resolve the problem. When I contacted Bluehost they reported it was a error 400 problem and the directories the selected URL was looking for did not exist.

To cut a long story short I asked Bluehost to restore a previous version of the site which was functional.

However, I am now back to where I started from even though the backed–up site which was used as the restore had been functioning perfectly.

So I am lost and need your help.

This is the current state of the site

.htaccess

# Use PHP5 Single php.ini as default

AddHandler application/x-httpd-php5s .php
