 * Is this something that I need to be concerned with? The text looks harmless to
   me.
 * Thanks for your help!

 * Forgot to add. This is the line of code the error above is referring to:
 * > // Now we set that function up to execute when the admin_notices action is 
   > called
   >  add_action( ‘admin_notices’, ‘hello_dolly’ );

 * You can safely ignore the php error log file in your /plugins/ folder.
 * 1. Go to the Ignore Hidden Plugin Folders & Files textarea box.
    2. Paste this
   into the textarea box: error_log 3. Click the Save Plugin Folder|Files Ignore
   Rules button.
 * It looks like you need to use the wp_footer hook instead of the admin_notices
   hook: `add_action('wp_footer', 'hello_dolly');`
