404 Error as I tried to save customized settings

Hi there.

I’ve just installed Writefreely on my own server. The installation went well, I can login, post and see my blog but I cannot save changes.

When I hit the button Save, I’m redirected to a page with the URL https://notepad.facb69.com.br/api/collections/fabio_oibaf and the message “404 page not found”.

The version is v.0.14, the latest.

Any help would be appreciated.
