Fatal error on activation, what does this mean?

Connections requires PHP 5, so solution will determined depending on who you have as your web host provider, but you can try the following:

First, try accessing your control panel and see if the option is available to change the default running version of PHP. If that option is not available, please ask you host provider to upgrade your account. If PHP 5 is available on your host and you still are receiving this error try adding the following to your .htaccess file:

SetEnv DEFAULT_PHP_VERSION 5
