Hi, I've added the grid for cases studies but this generates a warning.
I know this is just a warning but may be good to correct.
<b>Warning</b>: Invalid argument supplied for foreach() in <b>/rootpath/wp-content/themes/businext/loop/shortcodes/case-study/style-grid.php</b> on line <b>46</b><br>
Thanks to have a look.

Thank for your feedback. That is just warning message of php structure. Don't worry, it does not effect on theme functions.
You can hide it by turn debug off.
define( 'WP_DEBUG', false );@ini_set( 'display_errors', 0 );
The following code, inserted in your wp-config.php file.
