Solve the "Trying to get property ‘cnt’ of non-object" error

[leac]

On multi-site admin panels there is an error message: Notice: Undefined offset: 0 in /usr/share/nginx/html/eatsmart/wp-content/plugins/simple-custom-post-order/simple-custom-post-order.php on line 304. This is due to the face that no check is done on the resulting array from a query from the DB, and therefore when it returns empty and the code tries to access its cnt property, that error occurs. Therefore I added a check before the use of the array.

But maybe you should also check why that query is running, or why it's returning no results.
