How to Increase the Max Input Vars Limit?

PHP Max Input Vars means the maximum number of variables your server can use for a single function to avoid overloads.

The max_input_vars can be set by modifying multiple files. They are .htaccess, php.ini, .user.ini, or wp-config.php. files. You are gonna need FTP access to modify those files. You can find the credentials for your FTP access from your hosting provider.

To set max_input_vars please follow the steps given below,

1.Go to your WordPress root installation folder and locate any of these files .htaccess, php.ini, .user.ini or wp-config.php
2.Select any of the files above and Edit and paste the code given below,
3.Save the file.

It's better to ask the Hosting to increase this value.

					max_input_vars = 4000

for wp-config.php

					@ini_set( 'max_input_vars' , 4000 );
