If you specify upload_max_filesize in php.ini as plain integer (1048576 instead of 1M), the filemanager shows a max filesize of 0 Bytes.

Reason is a bug in filemanager.inc.php, the red line is the fix:

// Get the max upload size in php.ini
$max_size = ini_get("upload_max_filesize");
$multi = 1;
if (preg_match("/K/",$max_size)) $multi = 1024;
