Add the “index.php” before the “?p=”, “?cat=”, “?m=”…

Why do you want it to show up in every post?

Don’t think you can /index.php/?=anything

Links to pages have the domain/?p=
Links to categories or posts have the same…

Because they’re not all always on the index page…

You mention you’re working with a different folder…

so that wouldn’t change anything, I don’t believe. Quite certain it’s all relative, but your path would be example.com/foldername/ and it would either take you to index.php or whatever static page you’ve got set up… Even that doesn’t change the need for the lack of index.php and addition of /?p=

I am certainly no expert. But as far as I know that isn’t possible. All the pages that you create with write -> pages have an id, that’s how WP works. All your posts have an ID, same deal. You never link to index.php anywhere as far as I know… There isn’t any need for that. index is usually a default for the “home” page… Whether a regular html page or a wp page… so your http://www.whatever.com/folder/ would take you to the wp index.php. After that, index.php doesn’t make an appearance.
