500 Internal Server Error - after OJS 3 restored from backup


After a hard disk crash, I restored the website from a backup. I have an OJS 3.4.1, on a Debian 9, MySQL, Apache2, php 7.2 system.
The website seems fine, except when I try to download the PDF galleys from the articles, or the files inside the back-end - editorial workflow (where I get 500 Internal Server Error). For the PDF files there is an empty page.

For the files download from the editorial interface the following error is in /var/apache2/error.log
The files dir is correctly specified (identical with the backup). All the files are owned by www-data, and with 755 permissions.
I checked the file and it is in the correct place.
But what I find strange in the print screen is the fact there is a double slash after the journal number 1.

I have another OJS3 that using the same steps to extract from backup works fine.
And another OJS2 website that has the same problem.
Quite odd.

How can I get rid of this problem?

Thank you very much!


As usual with this error it is my error … I had saved the backup in a folder with the same name as the files_folder name so the path to files_folder was now incorrect. Sorry for the trouble!

And thanks for the great OJS system, and wonderful work you do!

Glad to hear you got it working.

:slight_smile: Thank you for the kind thoughts!
