During the upgrading to 3.1.1-4 I found in the log lot of warnings like this:
WARNING: Unable to find a match for “11-13-1-SM.doc” in “/var/www/ojs-uploads/journals/1//articles/11/”. Skipping this file.
The files are there (differently than OJS 3.1 Problems upgrading from 184.108.40.206 to 220.127.116.11) so I cannot understand where is the help.
Does anyone have any hints? How can I try to troubleshoot better the issue?
