error message

Thanks for this free plugin.
Testing and getting familiar with the plugin on my personal computer before posting to the web server.
But I get the following error. Using the default 2017 theme.

Warning: sizeof(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\wpmatrimony\wp-content\plugins\genie-wp-matrimony\application\views\profile\gwpm_pg_view_old.php on line 215

Could you kindly help in resolving this .
