Ed,
You’ll want to edit your wp-config.php file and find this spot (if it’s in there):
define('WP_DEBUG', true);
and replace it with this:
define('WP_DEBUG', false);
That should take out the unnecessary error message.
You can also add in a link to your text widget to direct your users to the URL of your choice. Just paste this where you’d like to have the link:
Just replace the http://yourlink.com with the URL you’d like to link to and Link Text with the text you’d like to turn into a link.
Hope that helps out. Let me know if you have any trouble,
Bill
