i recently did an upgrade from Magento 1.5.X to 1.7.X.
When I enter the Shop URL: example.com, everything is fine. The homepage is getting shown.
When I now try a link or try example.com/admin I get an 500 Error.
And knwo there is the interresting thing. When doing this: example.com/index.php/admin, everything ist fine too. Also when doing things like: example.com/index.php/some_other_site.html.
I hope someone could help me.
