No luck. After running the scripts, restarting Apache, Varnish & NginX, running sh /scripts/restart_cwpsrv, the upload_max_filesize did change on master (phpinfo) from 55 to 64M, but local stayed at 12M. Post_max_size also stayed at 12M on local (phpinfo). I had already manually changed /opt/alt/php-fpm74/usr/php/php.ini, /opt/alt/php-fpm82/usr/php/php.ini, /usr/local/php/php.ini in any case.
There is something somewhere setting this 12M value, but I'll be darned if I can find it!
Thanks for the input.
