I'm experiencing 2 issues which may or may not be related.
I have been importing the same CSV file a number of times using the File Upload mechanism and now when I try to upload a different CSV, the previous file is uploaded. I removed the file from the server, and tried to upload the new file, but I just get a message that the old file cannot be found.
As an alternative, I then tried to use the HTTP Fetcher to upload the new CSV file from the server. But although I have chosen to attach the standalone form in my basic settings for my importer, the input field for the url is not displayed - just checkboxes for Auto detect feeds and Use PubSubHubbub.
Can anyone help?
