.htaccess not working on localhost

it fixes the issue Change AllowOverride None to AllowOverride All for your web site directory:

<Directory /var/www/mysite.com/public_html/>
    AllowOverride All
    Order allow,deny
    allow from all
</Directory>

To fix the issue you can do You can put the .htaccess on the www folder and place the content on it:

Options +FollowSymLinks -MultiViews

RewriteEngine On

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+(.*)\.php [NC]
RewriteRule ^ /%1.html? [R=302,L]

RewriteRule ^abc/about\.html/?$ /abc/about.php [NC,L]

this will help In my code , I am using a function called run() (which is a user defined function) for checking a particular condition. When disabling that function everything working fine. Then I changed that function name to another name that time also works. I don't know why run() not working in server. But now my problem solved

around this issue I am fairly new to php and RewriteRules, I tried to make localhost/webapp/sign_up.php point to localhost/webapp/sign_up. This is my .htaccess code: , Try this and let me know

RewriteEngine On
RewriteBase /webapp/
RewriteRule ^([a-z_]+)/?$ $1.php [NC,L]

sudo a2enmod rewrite
sudo service apache2 restart
