IMCE browser just won't work (403 error) I've installed IMCE to the CKeditor 4.54.4 in Drupal 7.41 (all in latest versions) and configured it both from editor appearance and file browser settings.

Seemingly I did all by the book and there are no errors in the status report.

I flushed all caches and switched to the full-html text editor format.

I then clicked on the CKeditor image icon, and there on "browse files" button created by IMCE.

Than I got an error (translating this from Hebrew): "The page is not reachable" (403 error). The path of the window, if it helps is:

imce?app=ckeditor|sendto%40ckeditor_imceSendTo|&amp;CKEditor=edit-body-und-0-value&amp;CKEditorFuncNum=155&amp;langCode=en


Maybe you have an idea?
ן needed to configure the IMCE profile as a saparate configuration from the CKeditor-IMCE configuration.

Go to Admin > Files > IMCE and configure it.
