Solution: Symfony only first index page is working

Every new Symfony developer faces this issue when only the index page is working and any other links are showing "page not found" error. There needs to be some adjustments to your .htaccess file. 

Just copy and paste below code to your .htaccess file and problem should be fixed.

DirectoryIndex index.php
<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI}::$0 ^(/.+)/(.*)::\2$
    RewriteRule .* - [E=BASE:%1]
    RewriteCond %{HTTP:Authorization} .+
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%0]   
    RewriteCond %{ENV:REDIRECT_STATUS} =""
    RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>
<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>      
        RedirectMatch 307 ^/$ /index.php/      
    </IfModule>
</IfModule>
