AJAX Errors in WordPress Admin

Description
AJAX-based functionalities (e.g., media uploads, custom metaboxes) fail in the admin panel.

Causes
Invalid admin-ajax.php calls.
Plugin conflicts.
Nonces not verified.

Solution

• Debug AJAX Calls:
  Use the browser's developer tools to inspect the network request. Look for errors in the response.

• Verify Nonce Validation:
  Ensure proper nonce verification in AJAX functions:
  

if (!isset($_POST['nonce']) || !wp_verify_nonce($_POST['nonce'], 'your_action')) {
    wp_send_json_error('Invalid request');
}

• Increase PHP Limits: Increase execution time and memory limit in php.ini:

max_execution_time = 300
memory_limit = 256M
