See if you have this:

PHP Code:

// ###################### Start edit #######################
if ($action=="edit") {

  $user=$DB_site->query_first("SELECT *,FROM_UNIXTIME(joindate) AS 


If you do, replace it with this:

PHP Code:

// ###################### Start edit #######################
if ($action=="edit") {

  $user=$DB_site->query_first("SELECT user.*,FROM_UNIXTIME(joindate) AS 


This happened to somebody else I know when they installed a hack with the old version of the query.
