Today I have updated to 4.7.2.
The problem is resolved.

Thank you.

I have the same problem.

Before updating to the version 4.3 i didn’t have this problem.

Operating System : Linux (64 Bit)
Server : Apache/2.2.22 (Debian)
PHP Version : 5.4.39-0+deb7u2
libssh2/1.4.2

I need to hide answers from users that they can not talk correct answers to other users.
But sometimes need to see taking details if users want to see their mistakes after exam.

Here

if(empty($exam->dont_store_data)) {
		$wpdb->query($wpdb->prepare("INSERT INTO ".WATU_TAKINGS." SET exam_id=%d, user_id=%d, ip=%s, date=CURDATE(),
			points=%d, grade_id=%d, result=%s, snapshot=''", $exam_id, $uid, $_SERVER['REMOTE_ADDR'], $achieved, $g_id, $grade));
		$taking_id = $wpdb->insert_id;
	}

Taking saves if $exam->dont_store_data == 0. But taking saves without details because snapshot=”

Here

$output = str_replace($replace_these, $with_these, wpautop(stripslashes($quiz_details->final_screen)));
	if(strstr($output, '%%ANSWERS%%')) {
		$output = str_replace('%%ANSWERS%%', $result, $output);
	}
	$final_output = apply_filters(WATU_CONTENT_FILTER, $output);

$final_output will contain $result only if final_screen will contain %%ANSWERS%%.

i am not right?

I mean i want to see taking details as admin.

$final_output .= '<hr/>'.$result; # + line 146 of file cotrollers/show_exam.php
$wpdb->query($wpdb->prepare("UPDATE ".WATU_TAKINGS." SET snapshot=%s WHERE ID=%d", $final_output, $taking_id));
