upload_max_filesize

Hi all,
I edited the php.ini under /etc/php/7.0/fpm to have upload_max_filesize = 20M but when I try to import a file from phpmyadmin,I still have 2M maximum.
A little bit confused...What am I missing ?
PS: I also restarted php with /etc/init.d/php7.0-fpm restart

I'm surely missing something but be patient...
My OMV is listening on port 81, my nginx on port 8181 and phpMyAdmin on port 8182.
Is it because phpMyAdmin is listening on a different port that the nginx one ?

I also edited the nginx.conf file which is under etc/nginx adding to the http block the following :
client_max_body_size 20M;
but still have 2M for import file

Anybody out there who works with a database ?

PS: with MyWebSQL the maximum allowed is 25M...I still have to find out where it is set up
