My theme need to be updated

Hello Tungnx,

I received a warning on my WP saying:

Your theme (TravelWP) contains outdated copies of some WooCommerce template files. These files may need updating to ensure they are compatible with the current version of WooCommerce. You can see which files are affected from the system status page. If in doubt, check with the author of the theme.

Can you fix it? Cause I havent made a child theme.

How much will be?

Thanks!
