Yes this link is a dead giveaway that something is wrong with how your site is creating links:

The /index.php/ does not normally show up in a WordPress site. No .php or .html extensions are normal. WordPress creates a virtual link structure that you assign to it so everything looks pretty. Something is off.
@matthewhout may be correct that you’re on a windows IIS server. I’ve never used one so I wouldn’t really know.
I suggest you contact your web host and ask a few questions:
1. Do you have a working .htaccess file? You can tell them it should be in the root directory, same directory as wp-config.php.
2. Is the server correctly running apache?
