 * Hi, since upgrading to CF v4.6.1, I’ve noticed that CF7 produces the following
   error:
 * PHP Fatal error: Uncaught Error: Call to undefined function plugin_basename()
   in /nas/content/live/x/wp-content/plugins/contact-form-7/wp-contact-form-7.php:
   19\nStack trace:\n#0 {main}\n thrown in /nas/content/live/x/wp-content/plugins/
   contact-form-7/wp-contact-form-7.php on line 19
 * Any idea how to resolve this?
 * Thanks,
    – Asbjoern

 * OK. How did you install Contact Form 7 first time? And what other plugins and
   theme do you use?
