My munin graphs all of a sudden display n/a

I tried removing the RRD files, but they still display n/a.

I've run munin-check and it says it's ok.

How do I reset munin or what can cause this behavior?

Start by tailing logs in this order: munin-update.log, munin-graph.log, munin-html.log of the munin server.

I don't think it will be necessary, but here's some additional documentation on it:

The problem should be pretty clear if you take a look in the logs. Btw, removing the RRDs was probably not the best thing to do :-).
