Am Running K2 but I get an error

I am running Joomla 3.36 with the current version of K2. When I choose K2 I get the following error

Fatal error: Can't use method return value in write context in /home/peoplede/public_html/nct2/modules/mod_jux_news_wall/tmpl/Default/default.php on line 37

I also noticed that my options are different than those shown in the documentation.

Dear acqsys,
Thanks for contacting and choosing uour product!
About your problem with news wall please submit a ticket. Or you can go to line 37 then change:
<?php if($params->get('itemImage') || !empty($params->get('itemIntroText'))): ?>
to
<?php if($params->get('itemImage') || $params->get('itemIntroText')): ?>
Hope this help!
