• Welcome to WPSE, Alan. You're going to need to edit your question and provide some context as to what is happening. Be descriptive so people can help. Just posting an error without any context to it make it difficult for people to provide an answer. – butlerblog Commented Nov 29, 2018 at 18:52

This means you have a function named wp_my_admin_enqueue_scripts hooked to an action, either in your theme or a plugin, but that function name is not available to WordPress for some reason.

When that action fires, any functions "hooked" to it are executed by WordPress. If one of the hooked functions is not available, this is the error presented.

For example, in the sample code below the function named sc_corporate_widgets_init is executed when WordPress fires the widgets_init action.

add_action( 'widgets_init', 'sc_corporate_widgets_init' );

Make sure you do not have a spelling error with a function name. They must match exactly in order to prevent this error.

This error means that you have a wrong action (hook). meaning the code is trying to call a function that does not exists. But, from the path the error is coming from, I think:

1. you may have tried to change the core code
   
2. or more likley that your WordPress install is not complete, and you are missing files.
