I set up php5 and damaged the blog. Help.

I installed Apache and php5 (here configuration https://www.millionadvisors.com/php.php ) . Now the blog home page works (www.casino-folk.com), but when I click on categories or link to any topic (at the same time – admin works perfectly …). I get “The page cannot be found”. When I run previous apache (from other location) with php4 – everything works again.
Please help …
