How to remove a redirect in .htaccess - wordpress

Question

I need to build a website for someone, but it is currently redirecting to an appointment booking software. I checked the .htaccess file and there is some sort of redirect code, not sure how to remove it. I tried replacing the entire .htaccess file with a blank one, and every page on the site said "Page not found". Any suggestions? This is what is currently in the .htaccess file.
RewriteOptions inherit
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/\.well-known/cpanel-dcv/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/\.well-known/cpanel-dcv/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$

Answer 1

Any line with a RewriteRule and the [R] flag (in your case written as [R=302 for a temporary redirect and [R=301 for a permanent redirect) is a rewrite rule that tells apache to redirect to the given url. The RewriteCond lines before the rule modify when the RewriteRule after it is executed. In your case you have two redirect rules:
RewriteCond %{HTTP_HOST} ^suitezen\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.suitezen\.com$
RewriteCond %{REQUEST_URI} !^/\.well-known/cpanel-dcv/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule ^(.*)$ "https\:\/\/www\.massagebook\.com\/Bowling_Green\~Massage\~IBTsuitezenmedicalspa$1" [R=302,L]
and
RewriteCond %{HTTP_HOST} ^.*$
RewriteCond %{REQUEST_URI} !^/\.well-known/cpanel-dcv/[0-9a-zA-Z_-]+$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule ^(.*)$ "https\:\/\/www\.massagebook\.com\/Bowling_Green\~Massage\~IBTsuitezenmedicalspa$1" [R=301,L]
Delete those and delete the cache of your browser to see Wordpress again. I see that there are some conditions related to cpanel that are not usually part of a Wordpress installation (see the official wordpress site for an example of the default .htaccess). If for some reason the redirects get re-added to your .htaccess, dive into cpanel to see if there is a configuration option there.
