 * I’m not sure why this is happening on my site but when I submit post from front-
   end form, I get this error message.
    `Catchable fatal error: Object of class 
   WP_Error could not be converted to string in .....`
 * Anyone having the same issue?
 * Another error message I get on submit button on Edit post page,
    `Illegal string
   offset 'update_text' in <b>/wp-content/plugins/wp-user-frontend/class/render-
   form.php</b> on line <b>541`

 * I found why the first error showed up on my site.
    In previous version, it has
   a setting for default category but in new version you need to specify category
   on each form. If you don’t it goes to no category. (As far as I tested, it does
   not have any value for category)
 * That broke my breadcrumb rendered before the content cause it does not have category.
 * Just writing it down for someone who might have same issue.
