[Overgrow]

Does it tell you "No posts, please go back" ?

Does it give you a totally blank screen?

or does it at least show what forum you are in?

This change is just for eva to troubleshoot... FIND

echo spacer(2)."Dates: $date1 to $date2<br>&nbsp;<br>";

	$query = "SELECT title,threadid,lastpost FROM thread 
WHERE lastpost > '$ts1' AND lastpost < '$ts2' 
AND forumid='$forumID' ORDER BY dateline ASC";

change to

echo spacer(2)."Dates: $date1 to $date2<br>&nbsp;<br>";

	$query = "SELECT title,threadid,lastpost FROM thread 
WHERE lastpost > '$ts1' AND lastpost < '$ts2' 
AND forumid='$forumID' ORDER BY dateline ASC";

echo $query;

Then when it spits the query out, run it in phpmyadmin and see if it is a valid query.
