Excel spreadsheet upload error

[maurice941]

Once a Server Error shows up you can't import spreadsheets. The error is caused by an incorrect sheet, which is missing a name or other identifying information. I'm not exactly sure what triggers the error message itself, but the key issue is that as long as the error message is present, you won't be able to import a new (correct) sheet.
