Hallo

Ich bekomme bei meiner erst einrichtung von piwigo überall mysql fehler:

Warning:  [mysql error 3065] Expression #1 of ORDER BY clause is not in SELECT list, references column 'db37153.piwigovrmd_images.date_available' which is not in SELECT list; this is incompatible with DISTINCT

SELECT DISTINCT(id)
  FROM piwigovrmd_images
    INNER JOIN piwigovrmd_image_category AS ic ON id = ic.image_id
  WHERE date_available>=LEAST(SUBDATE(CURRENT_DATE,INTERVAL 7 DAY),SUBDATE('2016-06-11 13:25:17',INTERVAL 1 DAY))
  ORDER BY date_available DESC,date_available DESC, file ASC, id ASC
