hi again :relieved:
i have problem help me please

i move ojs folder with db from Linux server to dedicated server with windows server 2016

i change files_dir = “C:/wamp64/www/ojs”

So i want to change permission to 755 but Apache already has all the permissions it needs, as it runs under the LocalSystem account on Windows, which has extensive read/write access to local paths. This is inherited by PHP and the scripts it runs.

i can’t preview pdf or download it
please help me
what can i do?

Hi @fadia,

I’m not especially familiar with Windows’s permissions model – but I would suggest checking whether those permissions are sufficient by writing a quick test script containing e.g.:

<?php echo is_readable('/path/to/some-file.pdf')?'readable':'not readable'; ?>

Replace the path in ' quotes with the complete path to any file within your files directory. Then execute the script via your browser to see whether the files is readable. If not, you’ll likely need to work with file permissions.

Hi @fadia,

It appears that your files directory is a subdirectory of your OJS installation. Beware that this is a dangerous configuration, unless you’ve protected its contents from direct access via e.g. a .htaccess file. See docs/README in the “Recommended Configuration” section. This is also noted e.g. on the installation form.

Hi @fadia,

The best way to find out what directories OJS expects to find files in is probably to modify the files code temporarily to get it to log pathnames. Guiding you through that is a little out of scope for this forum, but you can start by editing lib/pkp/classes/file/FileManager.inc.php and adding to the start of the readFileFromPath function:

error_log('TRYING TO ACCESS FILE: ' . $filePath);

Whenever OJS tries to access a file, the path should be recorded in the PHP log file.
