After updating OJS from 3.0.1.0 to 3.1.1.4, I have following issues with my journal:
- On articles “Download data is not yet available.” is shown.
- At the bottom of the page, “Most read articles by the same author” is not working (shows “This plugin requires at least one statistics/report plugin to be enabled”).
Looking at other topics I’ve checked the following:
- both Usage Statistics and Recommended by Author plugins are enabled;
- UsageStats logs are processed each day and moved to archive and there are entries inside every log;
- metric in DB show counts for ojs::counter
I’m not sure where else to look for problems.
