CentOS 6 i386, two installs had that setting, I don’t remember running into that issue before, maybe something weird happened. They were on VMware using the CentOS minimal ISO.
Hmm, thus far I haven’t been able to reproduce that issue.
Do you know if, on either of those setups, any Virtualmin settings had been imported?
If there were settings from a virtualmin.tar.gz file that were imported, that could have brought in a Server Template that contained a Sub-Server plan containing that particular setup.
Another possibility, do you know if there was another repository of some sort that had been enabled? A third party repository could cause that sort of issue, if PHP were pulled in from there.
Out of curiosity, if you look in System Settings -> Server Templates -> Settings For Sub-Servers -> Apache Website, is the “Default PHP execution mode” option grayed out? Or are you able to select options from that?
If it’s not grayed out, what option is it currently set to?
The options are all filled in, like the settings were copied from the main template, here is a PDF of what the page looks like. No changes were made to anything.
Install centos -> update -> install.sh -> first run wizard -> look at default settings for sub-servers template
I have now seen this 6 times so far, I am checking other installs I have done recently as well.
