Missing BC Math or GMP extension in Laravel - php

Question

I am running Laravel 5.7.14 on PHP 7.2-fpm on Ubuntu 16.04.
My code in the local environment was working fine, but once I uploaded it to the production server I got this error message: Missing BC Math or GMP extension.
I have installed both GMP + BC Math. When I run the command php -i | grep -i bcmath I get this:
/etc/php/7.2/cli/conf.d/20-bcmath.ini,
bcmath
BCMath support => enabled
bcmath.scale => 0 => 0
When I run php -m I get this:

I have restarted the server multiple times and cleared Laravel's cache but nothing's changing, I keep getting this error message.
What am I missing here? If you need more info do not hesitate to ask.

Managing multiple PHP versions is sometimes very messy.
If you are on a Linux-like system and try to upgrade PHP versions you sometimes end up with 2 versions on the same system. Not infrequently (especially when you manually have configured the previous version) the newly installed version does not get enabled to use with the webserver. Personally I've also experienced upgrading PHP and getting the apache to use the new version but as a module instead of FPM so you should also be wary of that if you are using apache since again FPM and the PHP module for apache might have different configurations as well.
