Notice: Undefined index: highlighted in include() (line 124 of page.tpl.php I keep getting this error in a fresh drupal install with fusion and a custom fusion subtheme:

Notice: Undefined index: highlighted in include() (line 124 of /home/username/public_html/modules/system/page.tpl.php).


Would anyone happen to have any clue as to what is causing this?
If I am correct highlighted is a region name and you might have not defined it in you theme info file which is why it is throwing this error.

Give me more details of your info file and your page tpl file so that I can guide you in a better way.
