I have successfully installed the ISPConfig and it is working fine.
I have installed the additional PHP version using the following guide
Now I can select the PHP version from the admin and can change that to any domain created by me or reseller account.
But when I login via reseller account. I can not see the newly added PHP version in PHP Version dropdown. There is only Default Option
My question is, how can I allow the reseller or domain owner to change the PHP version for their own website
