Server Requirements

The following server requirements apply to the latest Sitellite releases:

Web Server:	Apache 1.3 or greater, configured with AllowOverride All or AllowOverride FileInfo Indexes (will require access to httpd.conf if this is not set correctly).
Other Web Servers:	Sitellite also runs in FastCGI mode on several web servers including Apache and LiteSpeed.  Apache + FastCGI should work out-of-the-box if Apache is configured correctly (see above).  Please see our installation troubleshooting pages for more examples.
Development Environment:	PHP 4.3 or greater compiled as an Apache module or in FastCGI mode (CGI-mode unofficially supported here) and also with CLI-mode enabled (--enable-cli, available by default since 4.3.0, however some servers have the CGI binary installed on the command-line instead of the CLI binary).
Database:	MySQL 4.1 or greater (if you run into any config issues, see here for MySQL 4.1 notes and here for 5.0+ notes).
Other Databases:	Oracle, PostgresSQL, SQLite, and others can be used as secondary data sources via Sitellite's database abstraction layer.  However, a MySQL database is required for the core web site functionality.

Some add-ons may have additional requirements, including:

SiteSearch	Requires PHP 5.2+
Scheduler	Cron command-line tools

Client Requirements

Sitellite supports the following list of browsers:

• Microsoft Internet Explorer 6 or greater on Windows.
• Firefox 1.0 or greater on any operating system
• Mozilla 1.7 or greater on any operating system
• Safari 3.0 or greater on Mac OS X or Windows.
  

We're hoping to add support for Opera and other browsers in future releases.

If you visit the Sitellite administrative login screen (www.yourWebSite.com/sitellite) with an unsupported browser, it will present an "Unsupported Browser" notice instead of letting you log in.  From the "front-end" of the web site, it does not, because your web site member usage likely doesn't have the same restrictions.
