Statistics broken

Question
1

Hi,
we have encountered this issues with statistics on privacyidea webui.

Privacyidea version: from 2.11 to 2.19 same issues.

After first days, i’ve noticed that when i load statistics from webui interface
i receive this error:

‘DataFrame’ object has no attribute ‘action’

This happens with every request i do on statistics section.

This is probably a problematic numpy version.

Ok, but i need a particulary version?

I’m using numpy==1.13.1.

Trying to restart Apache seems problems to be solved.
After a few days issue happen again.

Very strange.
