k sorry for the quadruple post.
Solved it !
If it can help anyone, this is my server-sided solution :
Edit /etc/apache2/sites-available/default
and change AllowOverride None to All (if you have it to “None” ofc), you should have something like this :
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
then /etc/init.d/apache2 restart
That did it for me.
My htaccess file keeps disappearing somehow, maybe someone is hacking me but let’s put that aside for the moment, my plugin works.
yay me
