Hello guys I need some help. Yesterday, my php codes works fine there's no error and have an output displayed in the browser. And this morning after running my new php code, the Firefox browser was a blank page only. So I've tried my other php files that works yesterday and they don't have an output. I can't figured out the problem. I can't post the screenshot of my works because I need 10 reputations to post an image. I'm new here in stack overflow I hope you can help me. By the way I'm using xampp. Thanks
