I first found it odd that .php files weren't associated with any browser. Then I opened the www directory index.php and it displayed as plain text, except for the regular html stuff. I was then even more surprised that I couldn't find other cases like mine ingoogle or even this forum.
What could possibly be wrong? Wamp seems to be installed and running flawlessly.
Actually I later found topics on this issue, but the problems were stated in such a confusing manner I couldn't get to it in time (and I was kinda desperate).
