HMVC broken in php 7.3 -- help

just change application/third_party/MX/Router.php line 239

from this 

PHP Code:

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


to this 

PHP Code:

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


tested 

To me this worked but with a little tweak:

PHP Code:

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