Hello,
1/
But when I updated it, the theme display becomes like I first installed wordpress
– sorry, but this is a bit unclear for me. Do you have any screenshots? Have you followed out docs https://xstore.helpscoutdocs.com/article/63-theme-update https://xstore.helpscoutdocs.com/article/37-plugins-update ?
As I can see, you are using 8.0.10 version of the theme, do you need our assistance to update it to 8.0.11? We can do this. Provide FTP access also. If you don’t know what is FTP then contact your hosting provider. They will give you access.
2/ To enable registration, navigate to Settings > General > Membership and mark Anyone can register, then go to Woocommerce > Settings > Accounts > Customer registration > Enable customer registration on the “My account” page.
