Illegal invocation message

Hi had several power outages when i was checking circuits at home , and unbeknown to me the EmonPi was picking up an error and not recording 2 of the CT and the 2 heat meters, powered the PI back up today and started recording all again, I do get this error message now when logging in
I click through OK but get the message on every page, Have cleared cache and history , any ideas ?

thanks Lloyd

Hello @lloree which browser are you using, I dont think this is an error that I’ve seen before and the randomised text string for the route is a bit strange… ?

Thanks Trystan have got home and tried it on Firefox and the same work site Edge and no signs of the error , please ignore and thanks both @TrystanLea and @glyn.hudson
