Call to undefined function?

After manuallyu upgrading, I get this when editing a post- the edit works, but it won't redirect back to the post...

any idea what's causing this?

Fatal error: Call to undefined function: unindexpost() in /home/hosted/warpstorm/public_html/forum/editpost.php on line 263

What version did you upgrade FROM and TO? unindexpost() was changed throughout the 2.2.x line.

(See, this is why you shouldn't upgrade manually unless you know exactly what's going on )

2.2.1 to 2.2.3, then I went from there to 2.2.4

OK stick this in your functions.php:

// ###################### Start unindexpost #######################
function unindexpost($postid,$title="",$pagetext="") {
	global $DB_site;

	// get the data
	if ($pagetext=="") {
		$post=$DB_site->query_first("SELECT postid,threadid,title,pagetext FROM post WHERE postid='$postid'");
	} else {
		$post['postid']=$postid;
		$post['title']=$title;
		$post['pagetext']=$pagetext;
	}

	// get word ids from table
	$allwords=$post['title']." ".$post['pagetext'];
	$allwords=preg_replace("/[\n\t\r,]/s"," ",$allwords);
	$allwords=preg_replace("/(\.+)($| |\n|\t)/s", " ", $allwords);
	$allwords=str_replace("[", " [", $allwords);
	$allwords=str_replace("]", "] ", $allwords);
	$allwords=preg_replace("/[\(\)\"':;\[\]?!#{}_\-+\\\\]/s","",$allwords);
	$allwords=strtolower(trim(str_replace("  "," ",$allwords)));
	if ($titlewords)
		$allwords.=" ".$titlewords;
	$wordarray=explode(" ",$allwords);

	$getwordidsql="title IN ('".str_replace(" ","','",$allwords)."')";
	$words=$DB_site->query("SELECT wordid,title FROM word WHERE $getwordidsql");

	$wordids="";
	while ($word=$DB_site->fetch_array($words)) {
		$wordids .= ',' . $word[wordid];
	}

	// delete em!
	$DB_site->query("DELETE FROM searchindex WHERE wordid IN (0$wordids) AND postid=$post[postid]");

}
