Problems with new Wordpress Site

RewriteRule ^$ index.php [QSA]
RewriteRule ^([^.]+)$ $1.php [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
and i have
DirectoryIndex index.html index.php

The above is the details i currently have

but when going to the actual site my index.html page shows perfectly
the index.php page does not show anything unless I type it into the address bar then it works
same with the wp-admin stuff for wordpress

any help is appreciate and if you need more info I would be happy to provide it
thanks
