emoncms empty rawdata

Hello,

 

I have my emoncms server working for a few days, but since yesterday, 2 of my feeds whent blank on the dashboard, rawdata, etc...

I can see them updating in the feeds, but the graphics are always empty.

 

I can see in Chrome console this:

 

Uncaught TypeError: Cannot read property '0' of undefined             realtime&feedid=1:208

getdp

 

 

Please help me!!!!!

 

 

Thanks in advance
