Content data changes to last year's view

Hi,

I did an upgrade on some of my OJS websites. From the version that is still the same OJS 3, the previous version was in OJS 3.1.x then I upgraded to OJS 3.3.0-19.

After some time, someone complained that some of the views on his website had changed and some had changed to last year’s content.

Is this possible caused by upgrade version ?

Hi @f666dhn,

Can you elaborate further on this on how it changed?
