We really need to have the answer to this in the install/upgrade instructions and any FAQ. The number of times I’ve seen this question about user.ini can/ .htaccess asked is getting a bit silly…
Anyway, @tx7 you’ll find the answer in this post. It mainly talks about the .htaccess file, but it’s the same problem, and the same solution.
Ok. Just make sure that you modified the correct .ini file being used (check with php --ini ) and that you restart PHP (sudo systemctl restart php-fpm if you’re using Systemd + PHP-fpm )so that the changes take effect.
