Hello Sahar Arafati
Try following steps.
Two steps required to create a home page.
You have to create two new pages manually as mentioned below. Go to Pages -> Add new
First page title : Home
Create a page with title ‘Home‘ and select ‘Home Page‘ in templates. No content required. Just publish.
Second page title: Blog
Create a page with title ‘Blog‘ and leave the template as Default template. Again no content is required. Just publish.
Go to Appearance -> Customize -> Homepage settings -> Custom home page: There select ‘A static page’. We are going to use the pages that we created in step 1. Select ‘Home’ in Homepage and ‘Blog’ in posts page. Publish. We have successfully set the home page. Now we are ready to tweak the home page content.
How To Edit Homepage Content?
Go to Appearance -> Customize -> Homepage settings. There you will see bunch of options to tweak your website’s homepage.
