Codeigniter 3 HMVC has been broken

Question

Using this HMVC plugin in Codeigniter. (https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc/src/codeigniter-3.x/)

Running fine in another server, but in this server I am getting this error!

A PHP Error was encountered

Answer 1

I change the line of codes on the function set_class like this:

    {
        //this is the original codes I commented
    /* $suffix = $this->config->item('controller_suffix');
        if (strpos($class, $suffix) === FALSE)
        {
            $class .= $suffix;
        }
        parent::set_class($class); 
    */

      //and change with this one
        $suffix = (string) $this->config->item('controller_suffix');
        if ($suffix && strpos($class, $suffix) === FALSE) {
            $class .= $suffix;
        }

        parent::set_class($class);
    }

Just Update the function in Router.php File Path: application\third_party\MX\Router.php

public function set_class($class)
    {
    //  $suffix = $this->config->item('controller_suffix');
    //  if (strpos($class, $suffix) === FALSE)

    $suffix = (string) $this->config->item('controller_suffix');
    if ($suffix && strpos($class, $suffix) === FALSE)
    {
        $class .= $suffix;
    }
    parent::set_class($class);
}

After this it is working fine!
