Which cache do I clear, and how? #

Caches make pages fast. Exponential renews them when content is published, so clearing by hand is the exception. Clear the smallest cache that solves the problem.

Who can do this #

Users whose role has setup/managecache.

Steps #

1. Choose the cache by what you changed:

   What changed	Clear
   A page shows old content after publishing	Content (content view cache)
   A template (.tpl) or a design file	Template caches
   A setting (.ini file)	INI caches
   You do not know, or several of the above	All caches

2. For a quick clear, use Clear cache in the right toolbar: choose the cache in the list and click Clear.

3. For more choice, open Setup > Cache management. The page Caches groups them: Content and views, Templates, INI and settings, Images, Pages, queries and the server, Other.

4. Click Clear content caches, Clear template caches, Clear INI caches, or the button of a single cache. Clear all caches clears everything.

5. Reload the page in a private window to check.

What can go wrong #

• The site is slow for a while after "Clear all caches". Every page is built again on its first visit. Clear all only when needed, and not at the busiest time.
• The page is still old after clearing. A cache outside Exponential holds it: the browser, a proxy or CDN, or the response cache of the web server. Reload with Shift held, or ask the host.
• A settings change has no effect. INI changes on the server also need the web server's PHP to reload. Ask the person who deploys.
