We'll create fresh WordPress site with Custom Error Messages for Gravity Forms installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin allows you to set custom error messages for Gravity Forms inputs. We support messages for Required, Unique and Email Validation errors.
In the settings of each form, you will find the Custom Error Message section. Here you can enable them for the entire form and set the default messages to be used for supported fields.
Use this option if you need to set a custom error message only for a specific field or to override the default message. Go to the Advanced Field Settings tab and you will find the Allow custom error messages checkbox. Once enabled, you can set a custom message for this field.
