Thanks so much! Now it works fine!

I guess steps to reproduce the problem should look like:

1. register new user
2. try to login (before using of confirmation link)
3. use confirmation link from email at least after 24 hours (maybe more) - it should tell you that it's expired
4. try to login and re-request confirmation email

I guess that reason is I configured celery improperly. The question is what parameters should we use to make celery working without redis (if it is possible)? Either it requires some other service instead of redis?
Sorry possible stupid questions but I hever used celery before...
