Menu Links add an extra “/”

I did a quick search for this topic but nothing came up related to what I was specifically looking for.

On my site, anytime I create a link to another part of the site, it adds an extra “/” between the link. For example when I create pages, the link may end something like “index.php/?page_id=3” or when I view commends it would look like “index.php/?p=1#comments” or maybe when I check out the archives, it would look like “index.php/?m=200505”.

It does this to all the links that link back to some other part of the site. I even checked Blog address (URI) in the options and it doesn’t end with a “/”.

So does anyone know of a fix that doesn’t add that extra “/” after the index.php?
