upgrade from 7.6 to 7.8.5


i tried to upgrade from7.6 to 7.8.5 but at the last step (Cunfirm Layouts) i get a white site after “Upgrade summary in processs”.

i activated all Errors on php but i only get this:

Notice: A non well formed numeric value encountered in /var/www/clients/client69/web231/web/crm3/include/utils.php on line 3472

the File Looks like this:

function return_bytes($val)
    $val = trim($val);
    $last = strtolower($val{strlen($val) - 1});

    switch ($last) {
        // The 'G' modifier is available since PHP 5.1.0
        case 'g':
            $val *= 1024;
        case 'm':
            $val *= 1024;    <-------------------------------------------line 3472
        case 'k':
            $val *= 1024;

    return $val;

Does some one can please help me?

Thanks a lot.

Bet regards


at the Moment i removed some old modules and i get this message:
