How to Increase the Max Input Vars Limit & WP memory Limit

Increase Max Input Vars

The max_input_vars directive can be set in .htaccess, php.ini , .user.ini or wp-config.php file. 

Directive for .htaccess

php_value max_input_vars 4000

Directive for php.ini or .user.ini

<strong>max_input_vars =4000
</strong>

Directive for wp-config.php

@ini_set( 'max_input_vars' , 4000 );<span></span>

Directive for wp-config.php

define( 'WP_MEMORY_LIMIT', '512M' );
