running envirement: Android 4.4+PHP 7.4.3+ KSWEB
http://192.168.1.2/tinyfilemanager.php, afer login,the main page could not be showed entirely,it just shows half of navigation bar.

that's becuase of
there are two same lines of codes which cause the problem. they are $owner = posix_getpwuid(fileowner($path . '/' . $f)); when the funciton fileowner($path . '/' . $f) return 0 and run the function posix_getpwuid(....) at next step, it trig an error. please check the codes in line 2156--2168 and 2221--2233.

suggest replace these two parts with followed codes:
$owner = array('name' => '?');
$group = array('name' => '?');
if (function_exists('posix_getpwuid') && function_exists('posix_getgrgid')) {
try{
$owner_id = fileowner($path . '/' . $f);
if($owner_id != 0) {
$owner_info = posix_getpwuid($owner_id);
if ($owner_info) {
$owner = $owner_info;
}
}

                    $group_id = filegroup($path . '/' . $f);
                    $group_info = posix_getgrgid($group_id);
                    if ($group_info) {
                         $group =  $group_info;
                     }

                } catch(Exception $e){
                   error_log("exception:" . $e->getMessage());
                }
            }
