Problem PDF Can't Show or Download

Hi, can anyone help me with this problem. So I have an article on http://jurnalbhumi.stpn.ac.id/index.php/JB/article/view/383/330
but the PDF file is not displayed (picture 1), when I check the path in the ojs-data/journals/1/articles/383/public file available on the server (picture 2). In the editor menu there is also the file (picture 3)

Server Information

OS platform Linux
PHP version 7.2.26
Apache version Not available
Database driver mysqli
Database server version 10.2.30-MariaDB

this problem is described here PDF error: Stream must have data
and second question you have merge public and files directive in config.inc.php?
all permissions are correct?

Configuration is appropriate, I try to delete PDF through the editor menu and check the file on the server is still there, then the article file on my server is deleted then re-upload it again through the editor menu, PDF can be displayed properly.

Hi @andrewdion04,

Can you confirm whether the old file and the new file both had exactly the same file and path name within your files_dir?

the path location exactly the same with old file, but the file name is different
old file name 383-1319-1-PB.pdf
new file name 383-1474-1-PB.pdf

Hi @andrewdion04,

Those are different file IDs, so actually totally different files. It seems as though the new file is simply missing. I would suggest putting a copy of the right file in the new location.
