How to Fix Warning: a form on this page has more than 1000 fields

Step1. Open php.ini file from your favorite text editor,

In my case location of php.ini file is /etc/php.ini 

Note:- The location may differ according to the PHP version.

Step2. Search line max_input_vars

By default the line max_input_vars will be commented, To enable uncomment by removing ;

; How many GET/POST/COOKIE input variables may be accepted
