Just noticed today that the “web mode” for our domain is only running under “PHP 4 CGI” which is no longer recommended by Dreamhost, and we are running EE 2 which says it requires PHP 5 or newer. Does this only affect CGI scripts or should I look to switch to PHP 5.2 or 5.3 for better compatibility with EE? If so, which version? Why was I even allowed to upgrade to EE 2 if it requires PHP 5?
