Cannot save Custom Fields in WordPress backend

Last Updated on: 5th May 2016, 08:27 pm

Sometimes custom fields fail to save. As a possible solution you can try and increase the max_input_vars which was introduced in PHP version 5.3.9. The default value for max_input_vars is 1000, which means that if your form has has more than 1000 inputs, any additional values will fail to save.

You can increase max_input_vars via your php.ini file:

max_input_vars = 3000

or via .htaccess document:

php_value max_input_vars 3000

And as always there is of course a plugin available that can help in checking your PHP version and editing your php.ini file. Here is one suggestion: https://wordpress.org/plugins/php-settings/
