Another 'folder not found' issue

Have you tried setting $baseUrl to "/ckuploads/" and checking whether CKFinder will discover the correct folder with:

$baseDir = resolveUrl($baseUrl);

?

The isue you've described always comes from invalid path specified. Perhaps /home4/ is wrong there and /home/ is correct?

No problem and my apologies for late reply. We should be able to check all the CKFinder posts more often now.
