the QuickSubmit Plugin “reorders” the issue archive when reloading the website or changing the language. This happens only to journals that started after an update from OJS 2 to 3 and use the QuickSubmit Plugin. Older journals, started with OJS 2, do not face this reordering.
Just hit F5 a few times and you will be surprised.
Where’s a good starting point to look for errors or irregularities?
