Please try to find exiting bug reports before adding a new one.

But this problem has not been solved for about an year and a half. I suggest simple and efficient solution of the problem.

For my solution to work at manual pagination too, one can set 'Questions per page' to 'Unlimited', which adds no automatic page breaks:

if ($perpage and $i > $perpage) { $layout .= '0,'; $i = 1; }

But it removes current pagination. To prevent this removing one should either prevent executing of the first line in the function quiz_repaginate. that is, change

$layout = str_replace(',0', '', $layout); // remove existing page breaks

to
if ($perpage) { $layout = str_replace(',0', '', $layout); // remove existing page breaks }

or simply return from the function if 'perpage' is set to 0:

if ($perpage) { return $layout; }

If you want to use manual pagination, you simply set 'Questions per page' to 'Unlimited'.
