Cannot login to Sendy after db / files restore.

Hi there,

I've been using Sendy for a few weeks with great results, so thanks for that.

Last night though, my server went down, and I had to restore the database and files from a backup taken 36hours ago.

Now when I go to login, I cannot access the backend at all. I just keep being redirected to www.example.com/login

I know that the username and password are correct because I use LastPass and have not altered anything.

I was wondering if you have any ideas about what might be causing this issue and how I might go about sorting it out.

Thanks for any and all help.
