How can I resolve this issue? Thank you.

The requested URL was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

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>
