I have changed it and still the same

Someone told me WP has actualy no /index.php
could be that the case? How can I change that?

Still I dont know the error is somewhere because of the WP Super Cache Plugin? and now its still redirecting?

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

# END WordPress

Black Studio TinyMCE Widget
Contact Form 7
Fast Secure Contact Form
Meta Slider
Page Builder by SiteOrigin
