Couldn't get mail server response codes. Please contact the forum administrator.
Note: For detailed error information (necessary for troubleshooting), enable "DEBUG mode". To enable "DEBUG mode", open up the file config.php in a text editor, add a line that looks like "define('FORUM_DEBUG', 1);" (without the quotation marks), and re-upload the file. Once you've solved the problem, it is recommended that "DEBUG mode" be turned off again (just remove the line from the file and re-upload it).
