The given page was not found. The reason was: The URL wasn't found in the module. The URL was: https://ssp-idp.example.org/simplesaml/module.php/statistics/showstats.php?rule=consentresponse&res=day&time=19421&language=en

How to reproduce 1) Go to /statistics Location 2) Try the "previous" link to come back to statistics of the day before

Number 1 and 3 have been fixed, but I'm not sure how to solve number 2. The more I try it, the more I'm breaking.. The reason for this error is that there is simply no data available.

Thanks @tvdijen ,

Is it not possible to catch this exception and show a message to the user indicating that data is missing?

[tvdijen]

I tried that, but I got a bunch of errors like issue 1 in return. When I tried fixing those, I ended up with a broken module..

Feel free to give it a try!
