I am working on my simple portal for specific, not top interest. I need ready to use CMS/Portal engine with easy possiblility to connect with my own php scripts.
Must be: - php only - free - simple and clear code or/and with well documentation - with good registration system - cms functions - safe as possible - simple template system
I know Joomla and other popular CMS systems not bad, but for this project I need something else. I don't want 99% of Joomla functions here and other reasons. I found some systems already, but waiting your opinion.
Drupal is good. It's much cleaner and less bloated than Joomla.
Honestly, it sounds like you need a Framework. You may want to look into Code Igniter, or CakePHP.
Good luck with your project!
