Update sydney theme

Hello!
I have not updated my website to Sydney theme version 1.45 as I am not sure if it will affect the changes I have made. Most of the changes were from your advice, but I am not sure if this affects the theme.

I have also NOT updated wordpress 2017 to version 1.6 for the same reason.

I update all my plugins regularly.

Can you advice?

Regards

Hi,

If you’ve saved the Custom Code as per our advice in a Child Theme or Custom CSS in Customize / Additiona; CSS, then you can update your Theme, your changes and your theme options won’t be lost, but in any case, please do a backup of your site before updating the theme and WordPress.

Kind Regards,
Csaba

I don’t know what a child theme is. I don’t think I have used custom CSS.
