ScalaHosting - 40 Common WordPress Errors and How to Fix Them

ℹ️ Despite appearances, WordPress is a complicated application that has more than a few requirements to run smoothly. Add the dozens of themes and plugins that some websites use, and you suddenly end up with an extremely complex environment.

Many components must work in unison for your website to stay online, which is a top priority for you. That’s especially true when you run a commercial project – every minute of downtime equals lost revenue.

That’s why trying to fix a crashed website can be so frustrating.
