There is a PHP notice message in json response.

<b>Notice</b>:  Trying to get property of non-object in <b>.../components/com_communityquiz/controllers/response.json.php</b> on line <b>158</b><br />

As per above notice, the line at 158 in components/com_communityquiz/controllers/response.json.php is

$pageId = $app->input->getInt('jumptopageid', 0);

The variable $app can never be null. So I assume you have some custom modifications here. Could you please post code from line 155 to line 160 in that file?

Hello,

No core files have been modified. I'll debug it and let you know.

Many thanks

The issue is: $response is null, set it's not been set. 

Change the duration if statement from:

if($duration > 0)

to:

if($duration > 0 && !is_null($response))

as a solution. You may know of a better one.

Many thanks
Tony

Can you send me the file?

As requested. This has been modified to if($duration > 0 && !is_null($response)).

Many thanks
Tony
