I had to add the following line to the end of my .htaccess file. This tells the webserver to user PHP5 instead of PHP4 (for anyone that doesn’t know). I had to do this with my other 1and1 hosted sites, including my Joomla sites.
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.
