upgrading problems

[kps]

I have ubuntu server , running nodebb 0.7.1

Via the admin panel Whenever i upgrade the plugins , it shows it as updated (hides the upgrade icons below the plugin)

I did nodebb upgrade here is what i get

26/8 17:45 [4049] - info: [database] Checking database indices.

After this when I refresh the plugins page , I see that no plugins have been upgraded, why is this happening ?
