I am trying to export and import an issue number between two OJS of the same version. When attempting to import, the following error appears:
SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (ojs4
.submission_files
, CONSTRAINT submission_files_source_submission_file_id_foreign
FOREIGN KEY (source_submission_file_id

(submission_file_id
) ON DEL) (SQL: insert into submission_files
(created_at
, file_id
, file_stage

) values (2023-12-29 13:16:37, 10, 11, 1, 49, 4, 2023-12-29 13:16:37, 1))
Any ideas?
OJS 3.3.0-3
