There are specific scenarios where you may need to change your PHP configuration. Specifically, you may need to edit a file on your server called php.ini, and increase the max_input_vars limit.
What is the max_input_vars PHP setting?
max_input_vars is a setting managed through the PHP setting, which limits the number of inputs you can set when posting forms.
While we do not allow global changes to the PHP.ini configurations on our servers , per account, PHP configuration changes can be made from cPanel by following these steps:
How to Increase the max_input_vars Limit in cPanel
The PHP Selector is omitted by default in cPanel and might be missing from your account if you are hosting with a different web host. All ChemiCloud customers should see the Select PHP Version section in their hosting account’s cPanel.
1) Log into cPanel.
2) Look for the SOFTWARE section and click on Select PHP version
3) Click on the Options link in the new window.

The PHP Selector is not included by default in cPanel and might be missing from your account if you are hosting with a different web host that’s not using CloudLinux.
Me also not seeing PHP_max_input_vars option !?!
If you are not a ChemiCloud customer, make sure that your web host is using CloudLinux as the operating system. If they do, then you should be able to find PHP Selector in cPanel then to jump to PHP Options.
If you are unable to locate max_input_vars then it means that your web host chooses to hide that option. Therefore you may need to reach out to their support and ask for assistance.
