Can't remember the username or password to your BCP
SOLUTION
1. Use FTP to download the config.inc.php from your /data folder
2. Open with notepad or your favourite text editor
3. Search for $gAdmin and $gPass, the values assigned to these will be your username and password respectively
Also make sure $gWebsiteName is not empty, for example it should be something like:-
CODE
$gWebsiteName = "yourdomain.com";
