Error Message: Notice: id was called incorrectly

My customer get Error Message after checkout return page."Notice: id was called incorrectly. " Please help me resolve this issues.

Hello There,

Thanks for writing in! You are seeing the PHP noticed because your debug mode is enabled. You will have to disable the debug mode to get rid of this message. You can do this by opening wp-config.php and adding
define( 'WP_DEBUG' , false ); just above /* That's all, stop editing! Happy blogging. */

For example:

define('WP_DEBUG', false);

/* That's all, stop editing! Happy blogging. */

When you revisit the page, you should no longer be seeing the message.

Please let us know how it goes.

@RueNel thanks for the quick reply. so far everything working fine & we did not receive the error message. Thanks again.

You’re welcome!
Thanks for letting us know that it has worked for you.
