is this query from the debug view?
because jdiction didn't touched this query.
So its possible that it was unable to parse it.
could you try to execute the query by hand?
just copy this code to the index.php in the template folder
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select("id, owner_id, title, userfolder, latitude, longitude");
$query->from("#__phocagallery_categories AS myCategory");
$query->where("owner_id = 852");
$db->setQuery($query);
$x = $db->loadObjectList();
print_r($x);
this should be translated.
if this doesn't work then there is a bigger problem with the jdiction installation.
after that please the ` to all fields like in your query and try again.
if this sill works, use this code:
$db = JFactory::getDbo();
$query = "SELECT `id`, `owner_id`, `title`, `userfolder`, `latitude`, `longitude` FROM `cwosjm_phocagallery_categories` AS `myCategory` WHERE owner_id = 852";
$db->setQuery($query);
$x = $db->loadObjectList();
print_r($x);
If this sill work then chronoforms does some unnice query string that couldn't be parsed by jdicion.
