It appears that either something went wrong or the mod rewrite configration is not correct.
If you don't use apache, just let .htaccess stay or create a empty file - then this check will pass.
We need to allow Apache to read .htaccess files located under the /home/sumperktv/public_html directory. You can do this by editing the Apache configuration file:
Find the section
<directory /var/www/html> and change AllowOverride None to AllowOverride All
sudo nano /etc/apache2/apache2.conf
After editing the above file your code should be like this:
<Directory /var/www/> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory>
In order to use mod_rewrite you can type the following command in the terminal:
sudo a2enmod rewrite
Restart apache2 after
sudo /etc/init.d/apache2 restart
sudo service apache2 restart
