I was using CKEditor 4.16.0 and received a security warning:
This CKEditor 4.16.0 version is not secure. Consider upgrading to the latest one, 4.25.1.
To fix this, I downloaded the latest version (4.25.1) and replaced the old CKEditor files via cPanel File Manager. However, when I checked the editor, the same security warning still appears.
I have already tried the following:
Cleared browser cache Cleared server-side cache Hard refreshed the page (Ctrl + Shift + R) Ensured that all CKEditor files were properly replaced But the issue persists.
Is there something else I need to do to fully update CKEditor and remove this security warning? Any help would be appreciated.

Reset to default 0Open your browser’s dev tools and check the loaded CKEditor version:
console.log(CKEDITOR.version);
This will tell you definitively if the browser is still loading 4.16.0. If it is, the update didn't take effect.
Some hosting environments (especially with cPanel) might have aggressive caching at the server/CDN level. Try renaming the CKEditor folder (e.g., from /ckeditor/ to /ckeditor-new/) and update your script tags to point to the new folder. This forces a fresh load.
Sometimes, not all old files get overwritten via cPanel. It’s safer to delete the old CKEditor folder completely and then upload the new version. This avoids leftover files from 4.16.0 interfering.
If you're using a custom build or loading plugins separately, make sure those are also updated to 4.25.1. An old plugin can trigger the warning.
