Date function error on web but not desktop

[zeel801]

I am getting the error "Somethings wrong with one or more fields: (Table) column"

It's odd though this only happens online and not on the desktop when I am developing the field.

I have the same problem. I have a measurement (a fomatted now()) displayed and also a graph containing a calculated column (including weekday()) that will both not show online. Does anyone have any suggestions?
