This error message is saying tha the menu.php file cannot be found in its expected location (CSSMenuWriter/cssmw_home/menu.php). Check that the file is there to be found. I see you are rebuilding your site from .asp to php - if you are setting off converting the original php files, make sure that you haven't got a menu.asp file instead of the menu.php version (your remote site has CSSMenuWriter/cssmw_home/menu.asp).
