Disable ssl/https redirection apache2 - php

Question

I recently enabled ssl in apache2 and everything was going well, but now everytime I try to access http://example.com/ I get redirected to https://example.com/
I checked my default.conf, apache2.conf for some directions but didn't find any.
<VirtualHost *:80>

<VirtualHost *:443>
DocumentRoot /var/www
ServerName example.com
SSLEngine on

SSLCertificateKeyFile /root/server.key
</VirtualHost>
I also double checked the .htaccess files in all directorys.
Is there a way to look up from where or what is redirecting?
Are any other ways to redirect ALL http requests to https?

Open Chrome Developer Tools, go to the network tab, click on preserve log, and load your site over http.
If you see a 301 or 302 redirect to https then something on the server is telling your browser to go to https.
If you see a 307 redirect to gyros then the site has, or had, a Strict-Transport-Security (aka HSTS) header set on it to force https and Chrome has cached that policy. This is a security feature web servers can use to enforce https. Check the HTTP Headers returned to see if that's the case and, if no such header is being sent than you can view and clear an old policy by using this page into your address bar: chrome://net-internals/#hsts
