WP 2.8 white screen of death weird or bug?

Hello, totally lost my site today, well not lost just white screens including admin ??

Followed all the tips and tricks for fixing white screens, none worked, called my isp, they saw nothing wrong. did the rename plugins,templates.. edited config.php, all to no avail!

I am running 8 plugins and all have been updated, my feeling is one of them corrupted some data.

I then went to mysql and removed the last post and the corresponding meta files.. Site came back to life.

Now I will add some new posts and see what happens. If anyone has run into this before and has located the plugin that MAY be responsible please get back to me.

Thanks
Bob
