After installing the site only shows a blank page with: Fatal error: Call to undefined function is_site_admin() in /home/content/24/7482924/html/wp/wp-content/plugins/buddypress-links/bp-links-admin.php on line 20.

I cant use wordpress anymore as it shows the same message.

Anyone have some idas about what I should do?

Maybe go into the site by ftp and disable buddypress links plugin

To disable, rename the folder `/buddypress-links/`

That should cause wordpress to de-activate the plugin.

Once you get back into wp, you can change the directory/folder back again!
