Hello,

Thank you very much for choosing our theme and for contacting us.

1. I need a sitemap for google index

Neither WordPress theme has this functionality, you will need to search for a plugin.

2. Avatar images of products are too small now. Please help me make it larger like avatar images of this web: https://yamahaguitar.vn/

You can change the images in the Theme Setings > Single Product > Images.

3. I can not change logo in mobile display

Please switch to the mobile view of the Header builder and change the logo image in the Logo element: https://xtemos.com/docs/woodmart/header-builder/header-responsive-settings/

4. When an order is made in my web, there is no notification email to my admin email.

Please make the full backup of your site and check the issue on the Storefront theme to detect if our theme causes the problem. Storefront is a free theme developed by WooСommerce.

5. I do not know why this part appear (file United1 attached)

Please try attach the screen, nothing has been attached.

6. In mobile display (file United 2 attached), 4 red columns do not stand in one straight line. Please make them in on straight line, to the left

Please provide the screen.

7. Please make text size in product content, in blogs… one level larger than present size

You can change the font by means of the Advanced typography option, which allows you to choose the item from a drop-down or insert your custom CSS class. Please navigate to the Theme Settings > Typography > Advanced Typography.

Here is the documentation providing more detailed instructions: https://xtemos.com/docs/woodmart/advanced-typography-settings/
