 * Hello
 * I’m new to wp and just finished an install on my VPS. It seemed all went ok until
   I installed a couple of themes and went to customize, which is causing the following
   error:
 * Fatal error: Call to a member function set_return_url() on a non-object in /home/
   quinju/public_html/_dev/homer/blog/wp-admin/customize.php on line 28
 * I turned on debug and see the following notice:
 * Notice: Undefined variable: wp_customize in /home/quinju/public_html/_dev/homer/
   blog/wp-admin/customize.php on line 28
 * Things that I tried so far with no effect:
    1) Remove the themes 2) Used the “
   reinstall now” option 3) Restarted apache
 * I’m running on Centos 6.2 / PHP 5.5 / WP 4.4.2
 * I have the similar setup running locally on XAMPP / windows 10, same WP release
   and there I don’t have the issue…
 * I’ve been googling it for the last 2.5h and found nothing so far, any leads will
   be greatly appreciated. 🙂
