Hello,
I’m using Open Journal Systems (OJS). When I try uploading files through the submission form, the server returns a response code 0, and the upload fails.
I’ve confirmed that:
upload_max_filesize
,post_max_size
, andmemory_limit
are all properly set- The upload directory is writable (
775
) - File names are safe (e.g.,
r_submission.docx
)
