Strange Errors

hello,
I have gotten the gallery to execute and am now attempting to configure. There are some errors at the top and bottom of every page..
The link to this is http://www.egr.msu.edu/~fsae/cgi-bin/gallery/index.php

#!/opt/bin/php

Confirm that the settings you entered came through correctly. There are errors highlighted below in red which need to be fixed before you can save your settings.

AT THE BOTTOM:
