.htaccess rewrite rule for same words - .htaccess

Question

I have two rules causing problems:
RewriteRule ^posts$ posts.php
RewriteRule ^posts/create$ postscreate.php
I know that I could use "post/create" but these are just two rules out of more that are having all the same problem.
I worked with this rules perfectly on localhost (XAMPP).
However, once I moved the files to my hoster and visited "sub.domain.com/posts/create" it redirects me to posts.php instead of postscreate.php.
Why does it work fine on localhost but not on my hoster? And how can I fix it?
My full .htaccess looks like this (with the two rules only):
AddType application/x-httpd-php .html
RewriteBase /
RewriteEngine On
RewriteCond %{SERVER_PORT} !=443
RewriteRule ^(.*)$ https://sub.domain.com/$1 [R=301,L]
Options -Indexes
RewriteRule ^posts$ posts.php
RewriteRule ^posts/create$ postscreate.php
The .htaccess on localhost is exactly the same except the https rules. I also tried the .htaccess without the https rules on my hoster but it still didn't work.

It is most likely due to option MultiViews being turned on on hoster but turned off on localhost.
To disable this use this line on top of .htaccess:
Options -MultiViews
Option MultiViews (see http://httpd.apache.org/docs/2.4/content-negotiation.html) is used by Apache's content negotiation module that runs before mod_rewrite and makes Apache server match extensions of files. So if /file is the URL then Apache will serve /file.html.
