 * Hi there,
    I´m about to set up a online shop. I worked a lot in the past years
   with the free version of the WPtouch plugin.
 * Now, as soon as I turn the plugin on – I recieve following warning ONLY on my
   mobile devices and ONLY when the Plugin is turned on and I’m sorting all the 
   products into categories. As long as I don’t run it with the single categories
   in it I don’t recive any kind of errors. In the browser on my laptop evrything
   appears the way it`s supposed to be.

 *     ```
       ** WARNING: explode()expects parameter 2 to be string, array given in /www/htdocs/w017a426/wildwest-merch.com/wp-content/plugins/woocommere/includes/class-wc-query.php on line 448 **
       ```

    Line 445 -451 look like this :
 *     ```
       }
   
       // Get order + orderby args from string.
       $orderby_value = explode( '-', $orderby_value );
       $orderby       = esc_attr( $orderby_value[0] );
       $order         = ! empty( $orderby_value[1] ) ? $orderby_value[1] : $order;
       }
       ```

 * Anyone an idea what could cause the issue? Thanks in advance for any kind of 
   help!

 * I recommend asking at [https://wordpress.org/support/plugin/wptouch#new-post](https://wordpress.org/support/plugin/wptouch#new-post)
   so the plugin’s / theme’s developers and support community can help you with 
   this.
