Chrome sometimes downloads a certain web page instead of opening it
There have been a couple web pages I attempted to access, but when I enter the URL in Google Chrome, it just downloads a website-like file titled "download" with an unknown file format. When I open this so called file in WordPad, it shows something that looks like a PHP file showing the webpage's structure. This site did open just fine a while ago, but now this problem persists. So what I'm asking is, what does it mean when your browser downloads a web page instead of opening it, and why? And I'm wondering if it's possible to fix it, and have Chrome open the web page instead of download it.
