PHP not working on denwer, why?

Decided to upgrade denwer.
Some have put apache2.4 and php5.6. Not processed php files, but that's right now managed in Apache Conf to prescribe treatment.
But I go here on the page and there are queries not working and just displays the text

PHP files are run, but the scripts/functions are not working.
What to do?

p.s. I'm just learning
