Since the mysql server on http://open.silverstripe.org/ seems to go down more often than a hooker from Ciranus IV:
Importing a CSV file into a mailinglist in the newsletter 0.4.0-rc1 module fails with: "Security token doesn't match, possible CSRF attack."
Steps to reproduce:
1. Go to <yoursite>/admin/newsletter/
2. Click Mailing List
3. Click tab 'Import'
4. Enter a (simple) CVS file with FirstName, SurName, Email columns
5. Click 'Show contents' button
6. Click 'Confirm' button
What happens:
The message "Security token doesn't match, possible CSRF attack." is shown.
What is the expected output:
CSV file is imported.
It could be that I am doing something wrong. But I'm using pretty much stock Silverstripe and newsletter.
