When an edit is saved but the public page still shows the old version, caching or editing the wrong file/location is often the first thing to rule out.
- Open the page in a private window or another browser.
- Clear the browser cache.
- If a cache plugin, server cache, or reverse proxy is in use, purge that cache using its documented controls.
- Confirm the edited file is inside the document root for the hostname being tested.
- Verify that the file on disk actually contains the new content.
- Check whether a CDN or other external cache is serving the page.
WordPress documentation specifically notes browser, server-side, and plugin caches as common reasons that changes seem not to take effect. Do not keep editing multiple copies of a file until you have confirmed which copy the live site is actually serving.
