Hi, looking at the debug log i noticed the following error:
PHP Deprecated: Unparenthesized a ? b : c ? d : e is deprecated. Use either (a ? b : c) ? d : e or a ? b : (c ? d : e) in /data/vhosts/******/httpdocs/wp-content/plugins/a-z-listing/widgets/class-a-z-listing-widget.php on line 75
What does this error refer to? and how can it be solved?
