# Warning: Creating default object from empty value / Cannot modify header informa

 * Hey WordPressers!
 * We’ve started getting variations of the below error, all pertaining to line 29
   in a theme file (the creators dont seem to be around anymore so I can’t contact
   them for support) and my php isn’t advanced, so I’m not sure what’s wrong with
   this line of code or how to fix it.
 * Example error:
    Warning: Creating default object from empty value in [datebase]/
   wp-content/themes/ronneby/redux_framework/ReduxCore/inc/class.redux_filesystem.
   php on line 29 Warning: Cannot modify header information – headers already sent
   by (output started at [datebase]/wp-content/themes/ronneby/redux_framework/ReduxCore/
   inc/class.redux_filesystem.php:29) in [datebase]/wp-content/themes/ronneby/inc/
   lib/CompileLess/CompileLess.php on line 39
 * Sometimes it shows other similar errors, but the offending line is always class.
   redux_filesystem.php on line 29
 * Line 29 reads:
    `$this->parent->admin_notices[] = array(`
 * The full code is:
 *     ```

   suggested here: [https://wordpress.org/support/topic/empty-value-warning-after-updating-php/](https://wordpress.org/support/topic/empty-value-warning-after-updating-php/)-
   php has been updated -updating wordpress & pluggins -disabling all plugins -running

 * I believe that you should be able to wrap the assignment with a check to see 
   if it exists before trying to set a value to it. Try this in your function:
 *     ```
       if (! empty($this->parent)) {
       		$this->parent->admin_notices[] = array(
       			'type'    => 'error',
       			'msg'     => '<strong>' . __( 'File Permission Issues', 'pinnacle' ) . '</strong><br/>' . sprintf( __( 'We were unable to modify required files. Please check your permissions, or modify your wp-config.php file to contain your FTP login credentials as <a href="%s" target="_blank">outlined here</a>.', 'pinnacle' ), 'https://codex.wordpress.org/Editing_wp-config.php#WordPress_Upgrade_Constants' ),
       			'id'      => 'redux-wp-login',
       			'dismiss' => false,
       		);
       	}
       ```
   
 * So you will add if (! empty($this->parent)) { above and a closing } after.
 * If this is a production site, you probably should also look into suppressing 
   warning messages from being output to the screen. It would make sense to log 
   warnings to a log file but not show these warnings and errors to the general 
   public. Here is an article related to this:
