I downloaded a template from github, it’s working fine in localhost (using xampp)
but when I uploaded the files and the database on Hostinger, it says “404 – not found”

The instruction of the template told me to specifically name the folder to “OnlineNewsWebsite” and the databse to “news-portal”. Do I have to change anything related to those names in the code?

this is my htaccess code:

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ OnlineNewsSite/index.php [QSA,L]

This is my index.php
