I am trying to create a Child theme with a Plugin ‘Child Theme Configurator’ to prevent my CSS changes from being lost when the Sydney is updated, my site is

When I go through the analysis, it gives the following warnings:-

PHP Debug output.

Notice: Constant WP_CRON_LOCK_TIMEOUT already defined in /home1/cecilshu/public_html/wp-config.php on line 91

Please contact this Theme’s author and report the items inside the box above. You may or may not be able to use this Theme as a Child Theme while these conditions exist.

It is possible that this theme has specific requirements to work correctly as a child theme. Please make sure you are using the latest version of this theme and check your theme’s documentation for more information.

Is this OK to proceed, or what else can I do?

Thanks Paul

Hello there,

The debug output indicating that the error isn’t with the theme as wp-config.php file belongs to WordPress’ core files. To verify, you can try creating a child theme with default WordPress themes like Twenty Seventeen enabled.

By the way, we have a basic child theme which you can use as a starter. Check it out and see if it helps.


Hi Kharis,

I have used the Sydney Child theme, to it looks good. I have edited most of it to suit my requirements, with the exception of the footer, where can I remove the info about "Proudly powered by WordPress | Theme: Sydney by aThemes. "

I can’t find it anywhere.



Hello Paul,

Removing footer credits is available in the pro version. It can be managed from Appearance > Customize > Sydney Pro: Extra options > Footer Credits.

Thanks, Kharis, unfortunately, $ are tight, maybe when my business is up and running?
