Graphing stoped showing

Hi, can some assist with this problem?

all my devices are doing this on all of the graphing

need to do a ./validate and paste it in here. Might explain your issues

Looks fine but those modified files i wonder if they are having an impact on this? Has it ever worked and if so can you roll back?

HI, don’t really want to roll back if I don’t have too.
just to show you something it did work fine and then just stopped I can see there is values under the graph but nothing is showing on the graphs. This is on all the devices.
