Configuration export fails with:
Error 250: Invalid SQL statement
Expression #1 of ORDER BY clause is not in SELECT list, references column 'providence01.ca_relationship_types.type_id' which is not in SELECT list; this is incompatible with DISTINCT (in Db->mysqli->execute())
Problem seems to be in app/lib/ca/ConfigurationExporter.php with query "SELECT DISTINCT table_num FROM ca_relationship_types ORDER BY type_id"
After changing "ORDER BY type_id" to "ORDER BY table_num", configuration export is successful.
