      PHP Max input vars limits the number of input variables your server can use for a single function. If your website is WordPress, I suggest you put the value of PHP max_input_vars: up to 3000. Usually, the value max_input_vars is set to 1000 by default.

      You can change the PHP max_input_vars value in the .htaccess or the php.ini file in the WordPress directory. Follow the steps to change the PHP max_input_vars:

      Top 3 Methos to update PHP max_input_vars:

      Update PHP Max_Input_Vars in .htaccess

      Find the .htaccess file in the root of your wordpress website directory and add the below line at last:

      htaccess file to update PHP Max_input_vars

      php_value max_input_vars 3000

      Update PHP max_input_vars: in php.ini file

      Find the php.ini file in the root folder of your WordPress. If you do not find the php.ini file, you can create the php.ini file in the root folder of WordPress installation and write the below line and save.

      php.ini file to update PHP Max_input_vars

      max_input_vars = 3000

      Update PHP max_input_vars in wp-config.php File

      Find the wp-config.php file in the root folder of your WordPress Installation. Just open it and write the below code and save.

      WP_config file location to update PHP max_input_vars

      @ini_set( ‘max_input_vars’ , 3000 );

      I faced the same issue a few months ago, but I fixed it through cancel. I think, it’s the fastest way to change the PHP max_input_vars. Please follow these simple steps:

      PHP max_input_vars change from Cpanel

      1. Login to your Cpanel
      2. Search for “MultiPHP INI Editor” and click there
      3. In the “Configure PHP INI basic settings,” choose your domain name (yourdomain.com)
      4. Now in the fourth row, you can find ” max_input_vars.”
      5. Update its value to 3000 and apply.
      6. Done

      PHP.INI File Method:

      Please add the following code in a file named php.ini. You can find this file in the WordPress root folder. If you did not found the file, you can create the file php.ini in the root folder and place the following line.

      max_input_vars = 4000

      .htaccess File Method:

      You can find the file named “.htaccess” in the root folder. Place the below code in the new line of htaccess file at last.

      php_value max_input_vars 2000

      When setting up some of the WordPress themes or plugins, you may see this kind of error messages. It asks you to increase PHP Max_Input_Vars in your Cpanel or theme. You may go through several options like htaccess, php.ini, wp-config or Cpanel. I usually use htaccess and wp-config method.

      htaccess method

      Add this code in htaccess file

      php_value max_input_vars 5000
