.htaccess configuration.

I am trying to simplify my .htaccess on public_html folder. Initially it was full of drupal related stuff but now I have cleared and wrote following only.

# BEGIN WordPress
RewriteEngine on
#
# Unless you have set a different RewriteBase preceding this
# point, you may delete or comment-out the following
# RewriteBase directive:
RewriteBase /
#
# if this request is for "/" or has already been rewritten to WP
RewriteCond $1 ^(index\.php)?$ [OR]
# or if request is for image, css, or js file
RewriteCond $1 \.(gif|jpg|css|js|ico)$ [NC,OR]
# or if URL resolves to existing file
RewriteCond %{REQUEST_FILENAME} -f [OR]
# or if URL resolves to existing directory
RewriteCond %{REQUEST_FILENAME} -d
# then skip the rewrite to WP
RewriteRule ^(.*)$ - [S=1]
# else rewrite the request to WP
RewriteRule . /index.php [L]
#
# END wordpress

# Set the default handler.
DirectoryIndex index.php

Problem is that I have to put extra “DirectoryIndex index.php” other wise my WP site say’s “Wait A Sec” and than redirect to https://www.domain.com/dp.

So not sure what is the problem here.

Appreciate your help.
