Hi,there is an error in falang file "booking_subject.xml" - in section translation filters.
So if yo check "created|modified" you get the error:
1054 Unknown column 'c.modified' in 'where clause' SQL=SELECT COUNT(distinct c.id) FROM j25_booking_supplement as c LEFT JOIN j25_falang_content as jfc ON c.id=jfc.reference_id AND jfc.reference_table='booking_supplement' AND jfc.language_id=3 WHERE ( c.modified>0 AND jfc.modified < c.modified)
