I’m having similar troubles. I’ve gone through the pre-install checklist, and my server is up to par and my WP install works perfectly. In an effort to keep it clean, I’m using the latest version of WP 3.1.3 with no other plugins/themes/mods/anything. I can install the plugin, but when I activate I get this:
“Safari can’t open the page “http://mywebsite.org/wp-admin/plugins.php?activate=true&plugin_status=all&paged=1&s=” because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again.”
At this point, the site itself and admin area are totally inaccessible. If I manually delete (or change the name) of the buddypress plugin in the plugins folder, all is returned to normal.
I’ve searched high and low and am not sure where to look. Any help is truly appreciated. THANK YOU!
