For some reason, I can install pretty much any PHP extension, except for mbstring. I have installed php7.1.14 via sudo apt-get install php7.1 and then installed all my required extensions with sudo apt-get install php7.1-mysql php7.1-json... etc. I did the same for php7.1-mbstring but for some reason it won't get loaded:
forge@staging:~/test$ php -m

I've already tried adding extension=mbstring and extension=mbstring.so to my /etc/php/7.1/fpm/php.ini and /etc/php/7.1/cli/php.ini but no succes. mbstring.ini also exists in /etc/php/7.1/mods-available:
forge@staging:~/test$ ls -l /etc/php/7.1/mods-available/
