BuddyPress.org

I’m also having a problem with activaing BuddyPress. I’ve just done a fresh install of WordPress 3.1.

I tried the automatic install from within WordPress and it just sits at the following message and doesn’t go any further. I’ve let it site for half an hour:
Installing Plugin: BuddyPress 1.2.8
Downloading install package from https://downloads.wordpress.org/plugin/buddypress.1.2.8.zip…

I’ve also tried to install manually. I’ve uploaded the “buddypress” folder to the “wp-content/plugins” folder and when I go into WordPress Plugins and try to activate, I receive the following message:
Error 500 – Internal server error
An internal server error has occured!
Please try again later.

I’m using 1and1 hosting…. any suggestions?

Thanks,
