Your background image does not repeat itself and therefore you’re having this problem. You can replace it with a taller one.

Can we get a link?

A simple solution would be using display none on that element;

Add this to your css file;

.sf-sub-indicator {
    display: none;
}

Do you use a plugin for that navigation?

* Add this to your css file to make the main menu text as you want.

nav#main a {
    color: black;
    font-weight: bold;
}

* And add this to center align the navigation menu.

nav#main ul {
    margin: 0 auto;
    width: 400px;
}

* Check your server logs to see if there are any errors.
* If you use cPanel you can find the logs under the logs section.
* The last option is to contact the hosting company and see if they can help you.

I would follow these steps;

* Remove any other WordPress installations on that domain and make sure multiple installations are not causing any problems.

* As far as I see, you have installed WordPress to a separate directory, which is actually fine. Just to make sure this is not the origin of the problem I would install WordPress to the main directory where your domain points. In your case https://sureskumar.com

Alright, that sounds fair. Thanks.

Are you using a custom theme or a modified functions.php?

Try this page https://wordpress.stackexchange.com/

Set the main directory (WordPress dir) permission to chmod 775 and install.php permission to chmod 777 and try again.

Can you please post the line 42 of your /wp-admin/index.php?
