Hi there.

Thanks for the great plugin, but I got following warning after installed it on my wordpress site:

FastCGI sent in stderr: “PHP messa
ge: PHP Warning: Invalid argument supplied for foreach() in /usr/share/nginx/ww
w/wp-includes/rest-api/endpoints/class-wp-rest-controller.php on line 298” while
reading response header from upstream, client: 31.7.245.53, server: , request: “OPTIONS /index.php/wp-json/wordpress-popular-posts/v1/popular

Please help.
