WAMP & XAMPP not working on my PC

I tired to run WAMP & XAMPP on my PC but both just opena blank page when I go to localhost
Both of them use to work fine on my PC before but now none of them are working.Is there a way to find what problem is there that both of them show blank page, and I tired to reinstall but same result.

 

try deleting the .htaccess file that might help

 

After testing several WAMPs, I stick with EasyPHP for its simplicity. There's a simple free guide available too.

have you got it pointing to a different port? have you tried opening the control panel and make sure that apache is running? xampp control panel doesn't always like running as a service, nor apache if you have messed with your windows setup...

 

same problem here too, simple hello.php file(in www folder on local host WAMP) shows blank page in browser.

 

same problem here, xampp shows that is working, apache started, mysql started, I give it some refreshes the same problem: the page is either blank or showing the php code on it. Any sugestions? By the way, it can be the firewall / router??
