Delete the .htaccess file in picuploads, the same thing happened to me.
And, to show only 1 random adoptable...
Find:
PHP Code:
// Begin the output of all the adoptables to the user...
$query = "SELECT * FROM ".$prefix."adoptables";
$result = mysql_query($query);
$num = mysql_numrows($result);
Replace:
PHP Code:
$query = "SELECT * FROM ".$prefix."adoptables";
With:
PHP Code:
$query = "SELECT * FROM ".$prefix."adoptables ORDER BY RAND() LIMIT 1";
And you will now have a random adoptable each time.
