# PHP Warning: property “post_type” on null

 * Hello
 * I would like to draw your attention to a **PHP warning** that occurs in your 
   plugin called **_Shortcoder_**. The PHP warning is caused in the file `/shortcoder/
   admin/tools.php`, on **line 54**.
 * This line of code causes the PHP warning:
 *     ```wp-block-code
       return ( $screen->post_type == SC_POST_TYPE && $screen->base == 'post' );
       ```
   
 * It happens when the variable `$screen` happens to be `null`. Then `$screen->post_type`
   can not be accessed and therefore the `return` statement itself fails.
 * To mitigate the problem I made the following change in your code:
 *     ```wp-block-code
       if ( null !== $screen )  return ( $screen->post_type == SC_POST_TYPE && $screen->base == 'post' );else  return null;
       ```
   
 * You can make whatever adjustment you think is best in this case for your code.
   I am just trying to direct your attention to this issue.
 * Sincerely,
   Gevorg
