- Open MultiPHP INI Editor.
- Select Editor Mode.
- Select the target domain or home directory.
- Edit the directives carefully.
- Save and test the site.
cPanel warns that invalid directives can make PHP scripts non-functional. The interface performs only limited directive-name validation, so a saved file is not guaranteed to be valid for the installed PHP version.
