I don't know why my computer display like that. Could you help me fix it to back normal. Thank you very much
This looks like you have a plugin or other browser related issue. Try opening it in a different browser. For example, I assume you're using Firefox so try opening it in Internet Explorer, Chrome, etc. If it looks correct there, it is a browser issue... Try finding out what plugin or addon is throwing off your page views. If it looks incorrect there it is probably a setting issue... I was not however able to find a setting to reproduce that. In my pure opinion it looks like either css or javascript is not loading. I see you have a notice that this page has encountered an error. My best guess is its a browser issue for you.
