check that you put the code in the class_bbcode.php file after this.

	* Returns whether this parser is a WYSIWYG parser. Useful to change
	* behavior slightly for a WYSIWYG parser without rewriting code.
	*
	* @return	bool	True if it is; false otherwise
	*/
	function is_wysiwyg()
	{
		return false;
	}

An not after this marked in red:

	* Returns whether this parser is a WYSIWYG parser. Useful to change
	* behavior slightly for a WYSIWYG parser without rewriting code.
	*
	* @return	bool	True if it is; false otherwise
	*/
	function is_wysiwyg()
	{
		return false;
	}
        }

So it should look like this:

	
	
	* Returns whether this parser is a WYSIWYG parser. Useful to change
	* behavior slightly for a WYSIWYG parser without rewriting code.
	*
	* @return	bool	True if it is; false otherwise

	function is_wysiwyg()
	{
		return false;
	}

There are two of these "}" in the code you search for at the end of it. Put the hack code before the very last one
