On every page besides / I get a 404 page, and not laravel's 404 page?

I have enabled mod_rewrite.
Here is my .htaccess:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
# Redirect Trailing Slashes...
RewriteRule ^(.*)/$ /$1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
and my /etc/apache2/siotes-enabled/000-default.conf:
<VirtualHost *:80>
    DocumentRoot "/var/www/html"
    <Directory "/var/www/html">
        AllowOverride All
    </directory>
</VirtualHost
If I go to joshharington.com/index.php/about it works, but if I just go to joshharington.com/about it doesnt so I have gathered that it is a .htaccess problem.
I don't know much about .htaccess, but this works on my localhost. What am I doing wrong?
