Hello, There seem to be a bug. When a user register and have to confirm email, this is the error user get upon click the confirmation link in email:  Thanks! Thia is an example of confirmation link: To complete your registration, please visit this URL: https://askfh.com/index.php?u=/user/confirm&user=Nicolae Cirpala&token=2a6588ac1b0a86911b28c4c2ed2b4e52 I have determined that the issue appears when a username with spaces is used upon registration. The fix should either automatically convert confirmation url spaces into %20, or forbid using spaces in usernames, I'd prefer the second, because i replaced the space with a %20 in the given url and confirmation was successful. Some people love using spaces in their personal IDs.
