Dear abo,

To fix this issue, please go to modules\mod_sj_contact_ajax\mod_sj_contact_ajax.php find code:

$layout = $params->get('layout', 'default');
$cacheid = md5(serialize(array($layout, $module->id)));
$cacheparams = new stdClass;
$cacheparams->cachemode = 'id';
$cacheparams->class = 'ContactAjax';
$cacheparams->method = 'getList';
$cacheparams->methodparams = $params;
$cacheparams->modeparams = $cacheid;
$list = JModuleHelper::moduleCache($module, $params, $cacheparams);

=> edit to:

$layout = $params->get('layout', 'default');
$list = ContactAjax::getList($params);

Thanks & regards!

Hi.
I think a better way of fixing this issue is to modify /modules/mod_sj_contact_ajax/core/helper.php by adding unset($list->profile) just before return $list; statement in getList() method.

if (class_exists('ContactControllerContact') && $contact_id != '') {
$ctrl = new ContactControllerContact();
$model = $ctrl->getModel('contact');
$list = $model->getItem($contact_id);
unset($list->profile); <-----------------ADD THIS LINE
return $list;

} else {
return false;
}
$list->profile contains some SimpleXML objects that are not used in this module later but can not be serialized during cache operations.

Dear newwebpr

Thanks for your solution.

thanks

that works good

for joomla 3.8.x
refer to:
/home/user/public_html/libraries/libraries/src/Cache/Controller/CallbackController.php
in line 188
replace
$this->cache->store(serialize($data), $id);
width
// $this->cache->store(serialize($data), $id);
or remove this line

Dear Sir

We updated this issue in the latest version of the module

thanks
