On the Stack Exchange Data Explorer site, when I try to request a
.CSV file for the query I've just made, I get the ASP.NET error "regurgitation" (I don't know that there's anything meaningful in the text, but I'll include it anyway):
Server Error in '/' Application.
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".
I get this in both Chrome and Firefox. I have tried it with 3 possible sites (SO, MSO, and SU) and 2 different queries.
