First, I cannot find a category to report bugs, so I put it in Networking…
Second, the bug.
RPI with IPfire 183. I am not sure what is wrong because this page was working yesterday. I assume I hit some rare bug, that was triggered by some rare condition. This is the screenshot of the bug:
I updated RPI from Ipfire core 184 to 185. I still see that many RRD charts are broken and are broken in different ways. Some charts, like “hw temperature” work but most of charts are broken. An example:

This is database related to screenshot (from the first post), it seems that DB is not corrupted:
