Relaunch as Composr CMS
ocPortal is now known as Composr after a relaunch and re-brand in early 2016. Upgrading from ocPortal v8/v9 to Composr v10 is supported. Current ocPortal users should also check the Migration roadmap for more information.
ocPortal is a free and open source content management system (CMS) written in PHP and based on a MySQL backend database. The software has been developed by British software developer Chris Graham since 2004, with contributions from programmers Chris Warburton, Paul Duffy and Philip Withnall, and designers Allen Ellis and Robert Goacher.
Bitnami announced the release of a new installer stack for ocPortal towards the end of June in 2009. Installatron, a plugin for hosting control panels also includes ocPortal within its list of included scripts. In early 2010 ocPortal was one of the first websites to use Facebook's Hiphop HP on a live site and in Production. ocProducts founder Chris Graham completed a number of tests and reported a number of bugs not yet found by Facebook.

Data and feeds
ocPortal's weak points have been noted as its relatively small community. Very few community addons or themes have been released for ocPortal  when compared to projects such as Drupal and Joomla.
Early versions of ocPortal were hit with a setback in the form of a HTTP Remote File Include security vulnerability which “presents itself when an attacker provides a remote path to the 'req_path' variable through the URL”. This security vulnerability was fixed in later versions and several processes were added to make any future vulnerabilities less likely.
ocPortal was originally released in February 2004  and the current version is Version 9.
