I tried to sign up for an account today using an email address for which an account was already registered. Obviously that should fail, but the following error was also generated at the top of the page.
[phpBB Debug] PHP Notice: in file /includes/functions_user.php on line 1477: file_get_contents(***REMOVED***) [function.file-get-contents]: failed to open stream: HTTP request failed![phpBB Debug] PHP Notice: in file /includes/functions.php on line 4282: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3490)[phpBB Debug] PHP Notice: in file /includes/functions.php on line 4284: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3490)[phpBB Debug] PHP Notice: in file /includes/functions.php on line 4285: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3490)[phpBB Debug] PHP Notice: in file /includes/functions.php on line 4286: Cannot modify header information - headers already sent by (output started at /includes/functions.php:3490)
That error says that our antispam system was overloaded. I don't think it had anything to do with the existing email address.
Our antispam system is a bit bulky, it checks your IP, email, etc. against some rather large blacklists which is also why it takes a while to load after you click Register.
Right now I don't see a real solution, the one time I tried turning it off, we immediately got a bunch of spammers and there is no real way to make it faster since checking the data against those blacklists takes as long as it takes.
