This constant is the setup for the
W3 Total Cache fragment caching protocol that W3TC requires for security reasons.
By default, we set this constant with a unique but basic security string. However, this is not considered a strong security measure.
If you actively use W3TC, it is recommended to override this value manually with a stronger custom string.
Note: W3 Total Cache is not fully compatible with the Geo Controller, and if you experience any issues,
please contact the W3TC support team directly.

define('W3TC_DYNAMIC_SECURITY', 'cfgeo_' . md5(get_bloginfo('url')));
}
How to change
You can define a custom secure string by adding the constant to your
wp-config.php file before WordPress loads the plugin.
// Stronger custom string for fragment caching security
define('W3TC_DYNAMIC_SECURITY', 'SOME_SECURE_STRING_YOU_CREATE');
Important: This value must be unique and unpredictable to prevent potential cache-related vulnerabilities.
