Hello, Sorry to hear that you're having problems with the article. However, the article you're referring to has nothing to do with whether or not your website will respond. The caching settings of the article tells your browser cache how long the files should be kept before being renewed (when you visit the website again). If you're having problems with the website, it may be related to paths or other issues - I can see a website popping up, but it has no graphics or formatting. This is typical of a website that has been transferred over and pathing is not setup correctly. If you're changing the OpenCart URL, then please review our tutorial article on this issue. If you continue to have problems, please explain what you have done. Did you install OpenCart recently? What version? Were you trying to move your OpenCart installation? Please provide us this information and we would happy to look into the matter further. Regards, Arnel C.
