Homepage shows up after clicking any link - routing problem?

If you didn't make any changes, it sounds like your host may have changed something.

I'm guessing the culprit is either htaccess or the uri_protocoll setting in your config.
A possible solution, since it works with a ?, is to just add that to your RewriteRule:

Code:

# if you had this:
RewriteRule ^(.*)$ index.php/$1 [L]

# turn it into this:
RewriteRule ^(.*)$ index.php?/$1 [L]

Let us know how that goes.
