One of the most panic-inducing issues you might encounter on your WordPress website is the 500 internal server error. It can appear on any page of your website when there’s something wrong with your site’s file system or its server. Whatever the cause in your case, the outcome remains the same – your site will be offline, for all to see.
Thankfully, there are a number of ways you can troubleshoot your WordPress website, even before knowing exactly what caused the problem. Often, something as simple as deactivating themes and plugins or creating a new .htaccess file will do the trick.
