Hello,

Please make sure that you have uploaded all the files specially the `.htaccess` file. Mostly 404 error is due to missing `.htaccess` file. Please double check and upload it again. _dot files are hidden by default on linux/unix system._

Other cause might be `mod_rewrite`, please make sure it's enabled and configure to use `.htaccess` from site directory.

Lastly check the `base_url` in `app/config/config.php` If you have enabled SSL then the base_url should start with `https://`

If all check and still can't find the cause, let me know the site and server details in private reply to check.

Thank you
