Blank page when downloading files

Hello. I’m with a problem when a user try to download a file appears a blank page. I read anothers issues like this here in the forum, mostly of them could be resolved fixing the files_dir configuration, but I looked up, and even changed the files_dir config, or checked the permissions, but the problem remains.

The usageEventLogs/usage_events_20170828.log is weird. When I try to get, for example, the path path[]=809&path[]=812 the log says that it was path[]=85 200.

Here is the log file. Note that there is no one op=download:

Just to contextualize, I’m doing a migration between server from a server running the OJS in a Docker Container + Apache. In this new server is setted up with Nginx. The OJS version is 2.4.6.

Hi @mrmorais,

The most common cause of plank pages on downloads is that the files_dir (as configured in config.inc.php) is incorrect, or that file permissions don’t allow OJS to access the contents there.
