missing PHP extensions. Hide detail

The best way to resolve this is to install the correct missing extensions. The exact fix depends on our server, your host, and other system variables. 
Our PHP extension help can get you started.

* - In some cases, you might have two PHP configuration files: one for the PHP command line and for the web server. If so, make the change in both php.ini files. For details, see the php.ini reference.
