Question

Is there any other option to AllowOverride all except edit /etc/apache2/sites-available/default, means I have more than two projects in my remote server when I edit default to AllowOverride all my 2nd project stops working and when I edit default to AllowOverride none vice versa.

I want to run both projects at the same time

Here is /etc/apache2/sites-available/default

<Directory /var/www/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>

Answer 1

You may specify AllowOverride for each folder of your two applications

<Directory /project1>
AllowOverride None
</Directory>

<Directory /project2>
AllowOverride All
</Directory>
