Blocks, news, banners, etc. are not displayed in Bitrix1c, how to withdraw?

Question

1C-Bitrix

Hello, Winn premium template was bought, the programmer installed and configured everything.
Now it's time to fill the site, but in the menu itself there are no blocks, news, banners, directions, etc., although they should have been filled with demo data of the theme itself.



+ Can't change site name settings.
All he said is that we are trying to change the settings for the portal and not for the store.
You need to open the stores menu and select the name of this store so that they appear.
According to Google requests, how to do this, there is nothing good, maybe someone can help?
