May be I got the answer as well… I was trying to delete the plugin without catering for the alternate theme… so may be the default them got deleted as well… and the next theme did not kick in. This I noticed when I deliberately enabled the twenty-eleven theme, the website cam back as normal again… Thanks for your prompt response… Your question,” What Theme?” set me thinking in this direction… and I learned something new… thanks much !!!

Let me re-create the scenario for the third time and provide you more details… here are the list of plugins and their versions…

BuddyPress 1.6.4 Activated
Collabpress 1.2.3. Activated
BuddyPress Default Theme 1.6.4 Activated

This time I tried something new… I simply deactivated the plugin… and opened the front-end. Got the white screen again. Without even deleting the plugin.

But when I re-Activated the plugin and refresed the page… the website came back again….

Now a 3 out of 3 times success rrate.

Hope this helps..

I was using the standard BP theme… that comes with the install… I was working on all default settings… hope this helps…
