• doublecheck if CI::$APP->config->item('controller_suffix') returns a value. The error says it returns null – Vickel Commented Feb 12 at 11:37
• What have you tried to resolve the problem? Where are you stuck? – Nico Haase Commented Feb 14 at 12:08
• CI::$APP->config->item('controller_suffix') does not return a value – Oscar Mgaya Commented Feb 17 at 9:45
• Then check why this happens. Also, please add all clarification to your question by editing it – Nico Haase Commented Feb 17 at 10:09

Already checked CI::$APP->config->item('controller_suffix') configuration. Is the 'controller_suffix' configuration loaded correctly?

One solution would be to create a config $config['controller_suffix'] = '';.
