In the Databse Viewer object, I found a programming error, which means that it can not open on all servers.
When the object is run, an error message appears: "Error Can not Get Row Count"
The reason for this is due to a syntax error in 2 files
 dbviewer.php
 and dbviewer.vdsc871s.php
 both in line 62.$count = $db->query("select count(*) as rows from tabel" . $where); should be changed to:
$count = $db->query("select count(*) from tabel" . $where);

Hope this could help someone.
