Page not found after setting default page

I just installed Vanilla forums for the first time. I've embedded it in a page on my website. I installed it in a folder at called www.mywebsite.net/vanilla_forums and embeded it into a page with the url www.mywebsite.net/forum

It worked yesterday, but today I'm getting:

Page Not Found
The page you were looking for could not be found.

This occurs at both the above addresses.

I was going through the various settings and I changed one that was something along the lines of 'default page' to be 'forum'. So I suspect that the error is because there isn't actually a page within the forum that is called 'forum'.

How can I recover now that I can't access any of the settings. I have access to the database and to all the files on the server.

Thanks

Try to go to /dashboard and it doesn't work, try to add /dashboard to the 2 paths above.
