Bypass your cache — Simple instructions
In most Windows and Linux browsers:

In Apple Safari:

  • Hold down ⇧ Shift and click the Reload toolbar button.

In Chrome and Firefox for Mac:

  • Hold down both ⌘ Cmd+⇧ Shift and press R.

To speed things up and conserve communications bandwidth, browsers attempt to keep local copies of pages, images, and other content you've visited, so that it need not be downloaded again later. Occasionally this caching scheme goes awry (e.g. the browser insists on showing out-of-date content) making it necessary to bypass the cache, thus forcing your browser to re-download a web page's complete, up-to-date content. This is sometimes referred to as a "hard refresh", "cache refresh", or "uncached reload". The rest of your cache is not affected.

When you encounter strange behavior, first try bypassing your cache. In most cases you can use the simple instructions shown to the right, or see the complete browser-specific instructions below. If this is not enough, you can try performing a "purge" of Wikipedia's server cache (see instructions below). If problems persist, report them at Wikipedia:Village pump (technical).

If you are editing templates, you may need to wait a few minutes before bypassing your browser cache in order to see the change in a page with the transcluded template.

In unusual circumstances, it may be worth clearing the entire cache (of your local browser).

Cache clearing and disabling

Chromium-based browsers (Google Chrome, Microsoft Edge, Opera, etc.)

To clear the cache:

  1. Go to the "Tools" menu (the three horizontal ellipsis on the upper right of the browser) and click on "History" (Shortcut: Ctrl+H).
  2. Click on "Clear browsing data…" (Shortcut: Ctrl+⇧ Shift+Del).
  3. Select the types of data you want to clear, and include "Cached images and files" option.

If you would like to keep the data in your cache but test Wikipedia without using it, you can use the private browsing option.

To disable the cache:

  1. Open Developer Tools (F12, Ctrl+⇧ Shift+I or Tools ▸ Developer Tools).
  2. Click on the horizontal ellipsis on the upper right corner of the Dev Tools interface and select "Settings" (Shortcut: F1).
  3. Check the "Disable Cache" check-box.

information Note: This method only works if the developer console remains open. Browser extensions are available for download that force the cache to be disabled at all times.

  2. Select "Temporary Internet Files" at the top, and click "Delete". (If Wikipedia is in your list of favorites, you may need to turn off the "Preserve Favorites website data" at the top of the dialog box.)
  3. Internet Explorer will now silently delete the items you have chosen. Once finished, the notification bar appears at the bottom of the screen, stating that the selected browsing history has been deleted.

Purging Wikipedia's server cache

The Wikimedia servers cache a version of articles. When improperly displayed content is contained in a template or other transcluded page, bypassing your own cache might not be enough. You may need to purge the server cache of old page versions.

The server can be instructed to refresh its cache of a page's contents with the action=purge web address parameter. Add this to the end of the address. For example, to purge this page, visit one of the following:

For pages you think may need to be purged on a regular basis, include ((purge)), which provides readers with an easily-accessible purge link. Don't put this on article space pages.
