Why is it risky to have an outdated website?

Updated on 2026-07-18

Many website owners don't realize the real dangers of not keeping their site updated. Security, performance and compatibility all depend on it.

What needs to stay updated

  • PHP version — the language WordPress is built on. An old version can make your site slow, insecure and incompatible with modern features. See PHP and updating it on WordPress.
  • WordPress core — every release includes security patches, performance upgrades and better compatibility. Skipping them opens the door to vulnerabilities.
  • Plugins — mini-apps inside your site. Out of date, they can stop working, cause bugs, or become an entry point for attackers.
  • Themes — an outdated theme can break your layout or stop working if it isn't compatible with system updates.

The risks of not updating

  • Hacking and data loss — a large share of hacked sites are running outdated software.
  • Broken or buggy pages — a single plugin or theme incompatibility can take the whole site down.
  • Slow load times and weaker SEO — newer PHP and WordPress versions optimize speed; falling behind hurts.
  • Problems with forms, images or payment systems.
