I'm trying to add a child theme to my wordpress installation. The theme the child should be based upon a theme called "nostalgia-landing" which is installed and works properly. I created a new folder called "nostalgia-custom" and added the the style.css with the following content:

Theme Name: Nostalgia Custom
Description: Nostalgia Custom is a responsive WordPress landing page.
Author: QuanticaLabs and Christoph Halang
Author URI: http://themeforest.net/user/QuanticaLabs?ref=QuanticaLabs
License: GNU General Public License version 3.0
License URI: http://www.gnu.org/licenses/gpl-3.0.html
Version: 2.0.2
Template: nostalgia-landing
@import url("../nostalgia-landing/style.css");

However, the theme selection in admin panel does not show my child theme and says "You only have one theme installed right now.". This is not true since there are the default themes. When I delete the child theme folder the default themes appear again in the selection.

Did I miss anything? Any ideas guys?



  • Can you add a directory listing or screen grab of files and folders in wp-content/themes ? – jnthnclrk Aug 22 '13 at 14:33
  • Can't post images directly since I'm a newbie but here is a link Screenshot – Christoph Halang Aug 22 '13 at 14:35
  • Thanks, looks good, now we would need to see the contents of nostalgia-landing/style.css. – jnthnclrk Aug 22 '13 at 14:37
  • Since I bought the parent theme it is a rather long file :-/ I tried removing the import statement in my style.css with no effect, still no child or default theme visible. – Christoph Halang Aug 22 '13 at 14:40
  • Screen grab of Appearance page ( /wp-admin/themes.php )? – jnthnclrk Aug 22 '13 at 14:41

Problem solved: My child themes folder and the enclosed files had permission 750 instead of 644 set. Changed the permission and everything is working!

Two things come to mind:

  1. Is nostalgia-landing a child theme of something (Nostalgia perhaps)? WordPress doesn't allow grandchild themes -- you can't have a child theme of a child theme. (Check the style.css file in the nostalgia-landing theme -- if there's a Template: line, then nostalgia-landing is a child theme. If that's the case, you'll need to make nostalgia-custom a child of the original theme.)

  2. Is this a WordPress Multisite installation? If it is, you need to Network Activate both your child theme and the parent theme. If you don't activate the parent theme, you can't use the child theme.

  • style.css is the only file required to create a child theme – JMau Aug 22 '13 at 16:29
  • Good point. Back to two. – Pat J Aug 22 '13 at 18:28
  • Hey, thanks for your thoughts on my issue, here's what I think: 1) No, there is no "template" line in nostalgia's style.css file. 2) I don't know exactly what an MultiSite installation is but my wordpress installation is the only one on the server and was recently installed. – Christoph Halang Aug 23 '13 at 12:50
  • This is Multisite. If you installed WordPress and didn't turn on Multisite, then that's not the issue. Your best bet might be to contact the theme developers that made your parent theme, and ask them about your problem. – Pat J Aug 23 '13 at 13:48
