Hi @ibolee,

I hope you are well today and thanks for posting here.

I tried to access your site but it’s not accessible and displaying the error message “This webpage is not available”.

Could you please make it accessible so that i can troubleshoot the issue?

Also please share the page URL from where you are taking the child theme code.

Kind Regards,
