WHAT IVE TRIED SO FAR
Delete the following file:-

app/etc/use_cache.ser <-- I could not find the file in ftp or ssh

then tried doing this Opened PhpMyAdmin
- Went to my database
- Clicked SQL
- Ran the following SQL Query:

SET FOREIGN_KEY_CHECKS=0;
UPDATE core_store SET store_id = 0 WHERE code='admin';
UPDATE core_store_group SET group_id = 0 WHERE name='Default';
UPDATE core_website SET website_id = 0 WHERE code='admin';
UPDATE customer_group SET customer_group_id = 0 WHERE customer_group_code='NOT LOGGED IN';
SET FOREIGN_KEY_CHECKS=1;

Answer 1

First, are you the only admin user?

Second, In your app/etc/local.xml, look for:

<admin>
    <routers>
        <adminhtml>
            <args>
                <frontName><![CDATA[admin]]></frontName>
            </args>
        </adminhtml>
    </routers>
</admin>

Does it say admin or something else?

Third, go in your core_config_data table and try to locate these variables (lines 226 + 229):

admin/url/custom admin/url/custom_path

Do you have any caching enabled, or have any redirects setup? Delete the Cache manually (var/cache/).

I would enable your server logs (a quick look at GoDaddy has this tutorial showing how to do it: Working with Error Logs

Attempt to turn on Magento Logging (it should be on for dev sites). You can do this by going into "core_config_data" and look for a dev/log/active. It should be set to 1 for logging (yours is probably set to 0).

I would also go further and turn on Developer Mode (which should also be on for dev sites). You can do this by going to your index.php file and changing this:

if (isset($_SERVER['MAGE_IS_DEVELOPER_MODE'])) {
Mage::setIsDeveloperMode(true);
}
#ini_set('display_errors', 1);

to this:

//if (isset($_SERVER['MAGE_IS_DEVELOPER_MODE'])) {
Mage::setIsDeveloperMode(true);
//}
ini_set('display_errors', 1);

After talking to the user, it turns out it was a file error. I referred him to setup a Diff of his core files and setup a version control system.
