Адаптация 2.3.6 к php 8

[vorskla]

Пытаюсь адаптировать свои форумы к php8. Дошел до авторизации, после ввода логин-пароля получаем 

 

[27-Jul-2021 18:18:14 UTC] PHP Fatal error:  Uncaught Error: Call to a member function simple_exec_query() on null in /home/vors01717457/public_html/ips_kernel/class_converge.php:188

Там у нас функция

 

public function converge_load_member($email)
	{
		if ( ! $email )
		{
			$this->member = array();
		}
		else
		{
		  	$this->member = $this->converge_db->simple_exec_query( array( 'select' => '*', 'from' => 'members_converge', 'where' => "converge_email='$email'" ) );
		}
	}

 

Где-то в simple_exec_query ошибка, но не пойму где.

 

function simple_exec_query( $a )
    {
    	return $this->build_and_exec_query( $a );
    }

function build_and_exec_query( $a )
    {
    	$this->build_query( $a );

    	$ci = $this->exec_query();
    	
    	if ( isset($a['select']) AND $a['select'] )
    	{
    		return $this->fetch_row( $ci );
    	}
    }

 

Благодарю за любую помощь.
