Previously, we've covered why it's essential to keep your WordPress website, plugins and themes up to date and the same rules apply to sites running any content management system (Drupal, Zencart, Joomla!, etc) but what if you don't? What, aside from the security implications, are there for your website?
First of all, you're going to have to update your website software at some point, let me explain. You can’t keep running an old version of your site software forever. Some day you’re going to want to use a new theme, and your new theme is going to require the latest version. Or you’re going to install a new plugin or module, and it will require an update before you can even start the process.
