Cannot login to CODEX

[Life's Killer]

I went to the Cooking section in the Codex and tried to login, but my login was not accepted, even though the same login is accepted here in the forums. Is it because of the space character in the middle of my username?

Forum login is integrated into the site, so if you're logged in here, you should be logged in on the site as well. Space character is allowed and works in both login forms (here and on the site).
Try to make a clean test. Open the site in Chrome in incognito mode and try to log in.
