# Illegal string offset ‘attachments’

 * [8 years, 9 months ago](https://wordpress.org/support/topic/illegal-string-offset-attachments/)
 * Eight months ago I posted this [issue](https://wordpress.org/support/topic/illegal-string-offset-headers/)
   about a warning that appears on the front end of my sites when activating the
   email log plugin.
 * I waited for a while (eight months!) to see if this had been fixed. Well, now
   I get three more warnings from the front end, eek. (I just updated the plugin
   to 2.0.2):
 *     ```
       Warning: Illegal string offset 'attachments' in root/wp-content/plugins/email-log/include/Core/EmailLogger.php on line 48
   
       Warning: Illegal string offset 'to' in root/wp-content/plugins/email-log/include/Core/EmailLogger.php on line 49
   
       Warning: Illegal string offset 'subject' in root/wp-content/plugins/email-log/include/Core/EmailLogger.php on line 50
       ```

 * The original issue that you reported and the current warnings that you have reported
   are happening because the argument array that is sent to wp_mail filter is not
   having the required fields as mentioned in the documentation ([https://developer.wordpress.org/reference/hooks/wp_mail/](https://developer.wordpress.org/reference/hooks/wp_mail/))
 * The reason why I am not checking whether these values are not available in the
   array before accessing them is because they are expected to be there according
   to the WordPress documentation.
 * My guess is that this is mostly caused either by another plugin that hooks into
   the wp_mail filter and changes it or by the plugin that generates these emails.
 * Even though these warnings are happening because of another plugin I will try
   to fix them in my code if possible since in the error message it appears as if
   the warnings are generated by my plugin 🙂
 * Thanks for reporting these issues. I have created another github issue to track
   this [https://github.com/sudar/email-log/issues/99](https://github.com/sudar/email-log/issues/99)
   and it will be released as part of the next release in a couple of weeks.
 * The original issue that you reported has been fixed and is already part of the
   v2.0.2.

 * We just released v2.1.0 of the plugin with additional checks to prevent the above
   warnings.
 * Please update the plugin and let us know if you still see any PHP warnings.

 * After re-activating, the problem is solved. Thank you so much for doing this.
   I’m happy to have email log back up and running on all my sites!
