Cannot Connect to MySQL Error

[SNK2713]

Ah okay, thanks, BMR777. I'll go ask them then.

EDIT: I contacted the HelpDesk at 000webhost, and they basically said I should use a different FTP, so I did.

I'm still getting those other two errors though. I know that I'm supposed to fill out some information somewhere, but I'm not sure what exactly.

Error 1:

Warning: mysql_numrows(): supplied argument is not a valid MySQL result resource in /home/a1916460/public_html/adoptables/inc/functions.php on line 183

PHP Code:

// We will be getting our links from the database...
 
$links = "";
 
    $query = "SELECT * FROM ".$prefix."links ORDER BY id ASC";
    $result = mysql_query($query);
    $num = mysql_numrows($result); 


Error 2:

Warning: file_get_contents() [function.file-get-contents]: Filename cannot be empty in /home/a1916460/public_html/adoptables/index.php on line 80

PHP Code:

$template = file_get_contents($file);
