I am in the process of creating a new map. I have no problem picking a data set, however whenever I try to change any of the data under Data View, I get an error message that reads "Oops, there has been an error saving your changes."
Also, when attempting to add additional columns, I get a message saying that a new column has been created but no new column appears. I am even unable to switch the column data type to an existing column. Instead I get the message "error changing column type: undefined method `fetch' for nil:NilClass". Any thoughts?
