Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'temasportparma_db.t.id_lang' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

                    SELECT t.`id_lang`, t.id_tag, t.`name`, kl.titolo_h1, pt.id_keywords, kl.testo_h1 
                    FROM ps_tag t 
                    
                    LEFT JOIN ps_keywords_tag pt ON (pt.id_tag = t.id_tag) 
                    LEFT JOIN ps_keywords_lang kl ON (kl.id_keywords = pt.id_keywords && kl.id_lang= 5) 
                    WHERE t.name LIKE '%vendita%accessori%eastpak%parma%'  GROUP BY  pt.id_keywords
