Warning: count(): Parameter must be an array or an object ....

What does this error mean and how do you get it off?

Error: "Warning: count(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\lib\plugins\pagequery\inc\pagequery.php on line 1124"

usage: {{pagequery> @tech_doku:software:ms_excel:tipps_und_tricks *; hidestart; sort=a,name; filter=!name:c_template; proper; display={title}; bullet=disc }}

Plugin was throwing the very same error on me, fortunately it is easy to fix.

Open pagequery.php and move line 1124 ($level = count($group_opts['key']) - 1;) to line 1139 (just before foreach($sort_array as $row) {).

Or edit it according to this diff:
