"Lost your password" function does not work

Please help! I’ve forgotten the password to my site https://www.nbfa.no.

When I press the “Lost your password link?” I’m only redirected to the front page of my site, instead of getting the opportunity to write my email address and have a new password sent there.

Is this a known problem? I can’t find anything about it. How do I get a new password sent to me, or a link to a password reset?

Is there any other way I can reset my password? I don’t have wordpress installed on my computer, or any files for the website on my computer, so as far as I undrstand a lot of the things in the guide on how to reset passwords, won’t work for me.
