Fixing Intermittent CKFinder “Unknown Protocol” Errors

Why CKFinder can intermittently try to open a <code>kcact:</code> protocol URL and how to track down the manager-side integration bug.

If CKFinder sometimes opens correctly and sometimes throws an “unknown protocol” error, the issue is usually in the way the manager integration launches the file browser action. Because it is intermittent, it often gets mistaken for a browser bug.

In practice this points to a fragile integration point between the editor and CKFinder rather than to content itself. Re-check the manager-side handler, the generated action URL, and any customizations in the bundled build before blaming the browser alone.
