Fatal error: Call to private Matrix

investigating

please run phpinfo() and let me know the PHP version.

suspecting PHP version incompatibility.....

This module was fully tested on PHP5. It doesn't support PHP4 because it uses advanced OO feature of PHP5.

@ckng: I'm quite sure it's the PHP version problem, so I mark the issue as 'fixed'. If it doesn't fix your problem, please feel free to reopen the issue.

Experiencing the same exact problem

Running recommender encounter an internal error. If it is due to PHP out of memory, or timeout, please use Drush script instead. Otherwise, please file an issue to the http://drupal.org/project/recommender

I'm not sure what happened. But the fix should work.
