Unable to link media in CKeditor
From the question details it is not clear if you're using the CKeditor module, or it you're using the WYSIWYG module in combination with the CKEditor library (so without the CKeditor module).

As a possible alternative to consider, I'd suggest you try this:


if you're using the CKeditor module, then replace the 4.4.6 ... version of CKeditor with some 3.6.x version of it (such as CKEditor version 3.6.6.1.7696), and see if your problem is resolved (the 4.x version is known to have "some" issues which don't exist in the 3.x version ...).
alternatively, use the WYSIWYG module (without the CKeditor module, but only using the CKEditor library with version 3.6.6, since WYSIWYG module does not support the 4.x version yet ...). In this case, you may also want to experiment with the various 'cleanup and output' options within /admin/config/content/wysiwyg/profile/your_txt_fmt/edit (with 'your_txt_fmt' the text format you're using, eg 'filtered_html').
