"https://stackoverflow.com/questions/18740419/how-to-set-allowoverride-all" made it:
In case you are on Ubuntu, edit the file /etc/apache2/apache2.conf (here we have an example of /var/www):
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
and change it to;
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
then,
sudo service apache2 restart
Problem solved, thank you for your help!
