Addon domain and second wordpress installation not working

Question

I already had a Wordpress installation in public_html/wp directory for my primary domain name lets say domain-one.com. Now I added an addon domain domain-two.com with root directory as public_html/govt. Now I installed wordpress again for domain-two.com within directory wp. So now I have below directory structure -

my first website i.e. domain-one.com was and is working fine. However if I go to domain-two.com/wp/wp-admin/ it doesn't show me login/dashboard screen instead below screen is shown.

In public_html/ directory there are .htaccess and index.php file (for domain-one.com), while in public_html/govt/ there are no such file.

Content of public_html/.htaccess file

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Content of public_html/index.php file

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */

/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp/wp-blog-header.php' );

What should I do so that domain-two.com shows login/dashboard screen?

UPDATE 1: After going through this article, I created an .htaccess file (and index.php) in public_html/govt folder and put the below content in it. I tried with content of root folder htaccess file as well. But still the problem is same in both cases.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /govt/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /govt/index.php [L]
</IfModule>

# END WordPress

Answer 1

Try to install WordPress manually. I had the same issue. Just download WordPress, extract it and then shift the whole WordPress files in this folder. If you have already created dB, then change the config.php else it will ask you for the db creation. I hope this helps.

Answer 2

I guess for each domain hosted :wordpress auto generate .htaccess file and in .htaccess file, code is also the same as you posted here. and else addon domains are added only with CPANEL: addon domain software like here:
