After trying to change the icon in the admin panel, i get following error:
Call to a member function isOpen() on null
Error should be caused by following line, but i havenāt changed it and canāt find an issue
<li<?php e($contact->isOpen(), ' class="uk-active"') ?>>
I did change the default language prior to this error as well. But changing it back does not help finding the cause of this error.
Can someone help here?
