hello

everything is going fine on localhost, but when going online, I get this problem:

PDO connection: I get this error message

Code:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[28000] [1045] Access denied for user 'rdisast_rdisast'@'localhost' (using password: YES)' in /home/rdisast/public_html/class.php:14 Stack trace: #0 /home/rdisast/public_html/class.php(14): PDO->__construct('mysql:host=loca...', 'rdisast_rdisast', '$XeB46L@e') #1 /home/rdisast/public_html/class.php(256): UNDP->__construct() #2 /home/rdisast/public_html/index.php(4): include_once('/home/rdisast/p...') #3 {main} thrown in /home/rdisast/public_html/class.php on line 14
but I am sure the username and password are correct.

Tha main page appears empty, but I get the previous message when I add the /index.php to the site url.
.htaccess file content:
