Sorry, but it didn't work completely.

Now I see that ETA is calculated on other steps, but still I got that error.
I looked inside the code and found that the cause is not directly the absence of private messages in the board.

The ETA function is the thing that messes up everything.
I got the error on its 4th line, where the division is. Maybe because PMs are none, but I couldn't deeply analyze the code


<?php
function eta_calc($start, $pos, $pc)

{

        $cur = time();

        $prg = $pos / $pc;

        $eta = ($cur - $start) / $prg * (10 - $prg);

        if ($eta > 60) {

                echo ($prg * 10) . "% done<br>\nETA: ".sprintf('%.2f', $eta/60)." minutes<br>\n";

        } else {

                echo ($prg * 10) . "% done<br>\nETA: " . $eta . " seconds<br>\n";

        }

}
?>

If $pc is zero, theorycally $prg is infinite and $eta is a finite number (equal to $cur-$start).)
