Hello,
In order to load modules selected in CloudLinux PHP Selector, you need to create /etc/cl.selector/symlinks.rules file with
the following content: php.d.location = selector
And run the command to apply changes:
# /usr/bin/selectorctl --apply-symlinks-rules
If PHP Selector configured appropriately but modules are not loaded, please submit a ticket to
https://cloudlinux.zendesk.com, our techs will check the issue in place.
