    The error seems not intermittent, but it does it always. Password will not help me while some file change is needed for further testing. There are two places where this error may occur. To rule out the place, change 
 echo '' 
. _MODULENOEXIST . '';  
in /index.php with 
 echo '' 
. 'start' . _MODULENOEXIST . '|' . $xoopsConfig['startpage'] . '|' . '';  
and in /include/common.php to 
 echo '' 
. _MODULENOEXIST . '|' . $_SERVER['PHP_SELF'] . '|' . '';
