I cannot replace file without FTP access.
Given only WordPress admin access, I can only delete your existing Evolve Plus Theme, and upload a new copy of Evolve Theme with the latest woocommerce updated templates.
Please let me know if this is Ok with you.
Please let me know if you have any modifications to your existing Evolve Plus Theme, I will NOT be able to do any backup for you. You will have to do the backup first.
By the way, I saw your woo child theme. It is not created correctly, you cannot copy all existing Evolve theme files with it, it will cause PHP fatal error, meaning a “white screen of death”.
Template overriding is only for templates and not function files.
You are recommended to engage a competent WordPress developer to assist you in setting up your child theme.
If your purpose of setting up child theme is for saving custom css code, I suggest you use WordPress admin -> Theme Options -> Custom CSS to do it.
Looking forward to your reply.
