CodeIgniter 3.0 Remote Hosting Issue?

It sounds like the issue may be related to how your server is handling URLs and the CodeIgniter framework. Here are some steps you can take to troubleshoot and potentially resolve the problem:

1. Ensure that the .htaccess file is correctly configured on your remote server. This file should contain the necessary rewrite rules to direct all requests to CodeIgniter's index.php. A typical .htaccess file for CodeIgniter might look like this:

RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

If your project is located in a subdirectory, update the RewriteBase line to reflect that, such as RewriteBase /subdirectory/.

2. Verify that your server supports mod_rewrite and that it’s enabled. You can usually confirm this in your hosting control panel or by contacting your hosting provider.

3. In the index.php file at the root of your CodeIgniter installation, ensure the $system_path and $application_folder variables are correctly set, relative to your setup.

4. Ensure that the file and directory permissions are correctly set on your remote server. Typically, directories should be 755 and files should be 644. Incorrect permissions can lead to issues like 404 errors.

5. Double-check the base_url setting in application/config/config.php. Make sure it matches the domain and path on your remote server page.

6. Review the server’s error logs to identify any specific issues. This can often provide clues as to what might be going wrong.
