Feeds visualization problem with Emoncms version 8.2.8 on raspberry pi

Hello everybody,

this is my first time on this forum so, first of all, I would like to tanks the emoncms and openenergymonitor development team for their great job.

I have two versions of emoncms installed on my raspberrypi, the old one (I don't know the revision because is not reported on the Admin tab) works very well but don't have all the new feature of the last one (version 8.2.8) that I installed some days ago.

On the 8.2.8 version I'm not able to visualize feeds in the feeds tab (on that tab appear only the Refresh feed size button).

Another problem is that I'm not able to see the processes already associated to an input when I push the configure button on inputs item.

For the installation of the 8.2.8 version I followed step by step the instructions reported on "Install on Linux (via git)" procedure without any problem.

Where should be the problem?

Thanks in advance for your support

Nicola
