Collect subscriber names and emails via built-in AJAX. Submissions are stored as WordPress Subscriber accounts after email confirmation (double opt-in). Manage them in Users > All Users and connect to tools like MailPoet, Newsletter Plugin, or Mailchimp for WP.

To fix the “AJAX requested name is empty, please try again” error, you should check your server settings to ensure the following configurations are properly set. These settings help improve performance and prevent potential issues with AJAX and request handling:

• memory_limit 256M
  This sets the minimum memory allocation for the server to run scripts. Setting it to 128MB prevents memory exhaustion errors.
• max_execution_time 60
  This defines the maximum amount of time a script is allowed to run before being terminated. Setting it to 60 seconds helps avoid timeout errors.
• post_max_size 8M
  This limits the maximum size of POST data that can be sent to the server. Make sure it’s set to 8MB by default to avoid data transfer issues.
• upload_max_filesize 8M
  This parameter controls the maximum file size that can be uploaded through requests. 8MB is generally sufficient for most upload operations.
• allow_url_fopen ON
  This setting enables scripts to access files via external URLs. It’s important to have this turned ON for certain AJAX operations and external request handling.

To check and modify these settings, you need to edit your server’s php.ini file and ensure the above values are configured correctly. After making the changes, restart your server for them to take effect.
