syntax error, unexpected $end

Tags on my site are leading to “Parse error: syntax error, unexpected $end in /web/partfaliaz/www/wp-content/themes/ImageBlogger/archive.php on line 66”
I’m on WP2.7 and using last version of simpletags.

I’m hosted on PHP5, Short_Open_Tag are off.
Here is the archive.php… I don’t see anything open that isn’t closed:

<?php get_header(); ?>
