problem with /%postname%

it give me correct url for example

https://www.widewebtrade.com/news/asian-shares-fall-as-focus-shifts-to-growth-concerns/

but the page give error message of “NOT FOUND”

i just found it and did it as below :

from host server control panel,
create new file call it .htaccess file
add all below inside it and save.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
