Hi there, thanks for making this software. I've enjoyed sinking my teeth into it. I am a bit new to actually logging into servers and making edits in bash commands. I can do cPanel / WHM all day long. I am currently getting the error: Your system misses a few PHP functions/extensions in order to use this feature. exec function must be enabled in order to handle the DKIM keys. When I go to generate DKIM keys for my emails and domains. I would like to enable exec() to fix this. I have root access to my server through Digital Ocean. I have access to WHM and cPanel. I have already edited the PHP.ini file in WHM, but I am told there is a different ini file in the PHP FPM settings...and I am unaware how to access it. If that is the problem...what is the best way to access and edit that file? If that is not the problem, does anyone have insight? Thanks.
