Webmin version: 2.111
Virtualmin version: 7.10.0
Operating system: CentOS Linux 7.9.2009

failed : PHP error log cannot be set in none mode

I researched this and found https://forum.virtualmin.com/t/cant-set-php-options-to-fpm-failed-php-error-log-cannot-be-set-in-none-mode/126503/2 . I tried that, which resulted in another "failure" notice, and didn't disable the "Apache website enabled" option like I asked:

If I then try and re-save as FPM, it still presents the same problem, though.

I wasn't able to re-produce this, but then again I'm testing with the unreleased 7.20.1 version. Maybe wait till we get that out and see if you still have the issue?
