Hello,

Please check your download and upload the `.htaccess` file to server. Mostly 404 not found errors are caused due to missing or empty `.htaccess` file.

The default `.htaccess` files contents are as following (I am adding the FAQ with other checklist suggestions too)

```
DirectoryIndex index.php index.html default.html
<IfModule mod_rewrite.c>

RewriteEngine On
# RewriteBase /spos/
RewriteCond $1 !^(index\.php|assets|install|update)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# For godady Shared Hosting Server uncomment the line below
# RewriteRule ^(.*)$ index.php?/$1 [L]

# Please comment this if you have uncommented the above
RewriteRule ^(.*)$ index.php/$1 [NC,L,QSA]

</IfModule>
```

**Why am I getting 404 Not Found error after installation?**

Please

1. make sure that your apache `mod_rewite` is enabled
2. check that `.htaccess` file is successfully uploaded and exists in the main directory of SMA
3. `base_url` in app/config/config.php is correct and have no spaces

If you are using godaddy, please visit the codeigniter official guide here. You might need to check and modify you `.htaccess` files too.
