The design of VaM HUB has changed a bit since the last time I visited this place, and now I am not able to find my reaction history. I want to find a plugin page to which I reacted.
I checked and it seems that I can only see things within the last week.
If you want to see the previous one, you'll probably have to contact the administrator.
I am not sure how long it's been since you last logged on, but as standard database cleanup user activity logs are not kept indefinitely. This is not a feature that has been changed or can be restored.
