I've just installed this on a couple of my sites, and I like it. ;-)
Some fixes, though...
The line:
Code:
<title>$vboptions[bbtitle] - HTTP Error $error</title>
should be:
Code:
<title>$vboptions[bbtitle] - HTTP Error $error[title]</title>
Without that fix, the title of the page was "HTTP Error Array". Now it's "HTTP Error 404: File Not Found".
Also, after "$headinsert" add this line:
Code:
<meta name="robots" content="noindex, nofollow">
Without that fix, search engines could store the actual error page in it's index.
