Synology no Statistics

I have install urbackup on my Synology DS118. The Problem ist the Statistik is empty. I have no chart. How can i solve the Problem.

Did a little research and got the following error message in Chrome.


Do I need to install another program on my Synology?
Maybe someone can tell me what.

If you scroll up a bit/copy&paste the error, please?

Thank you for help.
I copied the bug. (1.5 KB)

Also a photo with the missing statistics

Also an error in the quantity (2.2 KB)

Looks like statistics calculation is not running for some reason (perhaps the server log file has some more info)

Here is the server log file.

Can it be that I have to create a user “urbackup” at Synology.
