Cache

What is caching in TYPO3?

Caching is a process TYPO3 uses to temporarily store content and data to help your website load faster and perform efficiently. Instead of regenerating every page or content piece each time a visitor loads it, TYPO3 saves a "cached" version. This way, the system can quickly serve this saved content, reducing the load on the server and speeding up the response time for users.

How to clear caches in TYPO3?

When you update content or make configuration changes, TYPO3 sometimes needs a cache refresh to reflect these updates on the live site. Here are the main ways to clear caches in TYPO3 13:

  • Clearing Cache in the backend:

    • In the Backend, look for the Clear cache icon, which resembles a lightning bolt. You can find this in the top toolbar.

    • For deeper cache management, you can use the Install Tool: In Admin Tools > Maintenance you can find the option to clear all caches. This will refresh everything, including caches that aren't typically cleared through the backend toolbar.backend
  • Clearing caches via Command Line

    For advanced users or developers, caches can also be cleared from the command line:

    ddev typo3 cache:flush
    Copied!

When should you clear caches?

  • If new content, images or text doesn't show up right away.
  • When adjusting templates, extensions or system settings.
  • While working on custom code, plugins or during site updates.
