                GROUP BY component_type [nativecode=1055 ** Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'civicrm.civicrm_mailing_component.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by]


After deactivating 'ONLY_FULL_GROUP_BY' in mysql with

msql &gt; SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));


it works...
