 * Hi [@ita21](https://wordpress.org/support/users/ita21/)
 * Just pass your function in **action hook after_setup_theme**
 * Like this
 *     ```
       add_action( 'after_setup_theme', 'constants' );
   
       function constants() {
         $blogValue = get_option( 'blogs_creators', '' );
         define('BLOGS_CREATORS', $blogValue );
       }
       ```
   
 * Thanks
