We’re running OJS 188.8.131.52 with two journals on a subscription model and others on Open Access - we recently noticed that some article galleys that should be locked behind a subscription can be opened and downloaded freely, while others articles of that same journal are locked normally.
We couldn’t figure out a pattern and there is no error in the logs, but after some research, it seems that a purchase from one user unlocks the galley for download from anyone.
We were originally on 184.108.40.206 when we noticed and updated to 220.127.116.11. to see if that might fix the issue. It didn’t.
The button indicates that the articles should be locked, but clicking it grants access to the galley. https://imgur.com/a/QerYpsC
