Not able to access manager after deployment

Hello, I am new to MODX and I am trying to deploy my development site to an external server. The site works fine after uploading it; however, I am not able to access the manager. When I put in the password, it parses, but the CMF login screen remains. If I put in the wrong password, I get the error message. I tried an upgrade and an advance upgrade using MODX Evo 1.0.6 install files, but I am not able to get a database connection using either even when I create config.inc.php manually. I tried changing the paths in the MODX configuration through the db manually, but none of the changes are recognized. I am not familiar with setting up the htaccess file. I appreciate any help, Thank you!

Platform Type: Debian
MySQL Version: 5.0.91-log
PHP Version: 5.3.13
Server: Apache

I've had this problem before, but it's been a long time since I've seen it.

I'm a bit foggy what the solution was but I want to say it was a file/folder permissions issue. Are you using FTP to upload the MODX package?
Sometimes that has bad results with permissions. Better to upload it via filemanager.

Here's a post where Susan gives some ideas and links to more help:

The site works fine after uploading it

Did you check config.inc.php on the hosting server ?
It's settings are different from your local setup:

$database_type = 'mysql';
$database_server = 'localhost';
$database_user = 'username';
$database_password = 'password';
$database_connection_charset = 'utf8';
$database_connection_method = 'SET NAMES';
$dbase = '`database`';
$table_prefix = 'modx_';
