vSlider WP Debug – Notice: Undefined Issue – Whitespace Problem

[DISPLAY_ULTIMATE_SOCIAL_ICONS]

Using WP-debug to troubleshoot an issue with a plugin, I was getting an error that read something like:

Notice: Undefined index: page in DIR\functions.php on line ###

and

WARNING: wp-includes/functions.php:### – Cannot modify header information – headers already sent by (output started at DIR/vslider.php:###)

The “Notice” issue can be resolved by adding following these directions: https://www.paulcracknell.net/434/notice-undefined-index-page-in

The “Warning” issue can be resolved by applying the same fix as the “Notice” issue as well as checking for something known as the “Whitespace Problem” which is described here:

If you happen to be using vSlider, and you are encountering the same debug errors, replace your “functions.php” file in the folder /wp-content/plugins/vslider/ with this file (zip compressed): vslider.php
