Why does Chrome keep showing old version of website?

Flush the DNS cache

If when visiting your site's domain in your browser, you are still seeing your old website come up (even hours after the correct DNS settings were entered), it may be that your computer or network is still using the old (cached) DNS information for your site.

Why does my browser keep opening old tabs?

Chrome doesn't fully shut down when you exit it. You may have noticed this since you still receive notifications on your system tray from websites and extensions even when Chrome appears closed. And, this functionality has the potential to glitch old tabs from reloading automatically at startup.

How do I stop Chrome from opening old tabs on startup?

To disable this feature, once again go into the browser's settings. Once you're in there, go to the section called On startup. See if the option that says Continue where you left off is selected, if it is, click on the option that says Open the New Tab page.
