Hmm, can I just remove this:
echo "<html><head><title>$vboptions[bbtitle] Database Error</title>";
echo "<style type=\"text/css\"><!--.error { font: 11px tahoma, verdana, arial, sans-serif; }--></style></head>\r\n";
echo "<body></table></td></tr></table></form>\r\n";
echo "<blockquote><p class=\"error\"> </p><p class=\"error\"><b>There seems to have been a slight problem with the $vboptions[bbtitle] database.</b><br />\r\n";
echo "Please try again by pressing the <a href=\"javascript:window.location=window.location;\">refresh</a> button in your browser.</p>";
echo "<p class=\"error\">An E-Mail has been dispatched to our <a href=\"mailto:$technicalemail\">Technical Staff</a>, who you can also contact if the problem persists.</p>";
echo "<p class=\"error\">We apologise for any inconvenience.</p>";
... and use a include("filename.php") string instead?
