How to increase PHP “Max Input Vars” Limit

The max_input_vars can be configured in your .htaccess, php.ini or wp-config.php file.

We recommend to increase default value to at-least 3000.

Here are 3 ways you can do it:

.htaccess

php_value max_input_vars 3000

php.ini

max_input_vars = 3000

wp-config.php

@ini_set( 'max_input_vars' , 3000 );
