I just purchased this to add into ckeditor running in a Zencart shop.
Uploaded the files, but your instructions for install are not very clear. You refer to files that are either not there or you refer to a file that is there without saying where in the file any content should be placed.

I have tried going direct to the uploader file but I get a blank page with the following source information

<script type="text/javascript">window.parent.CKEDITOR.tools.callFunction(, '', 'Resource type (type) is defined incorrectly ()');</script>

Thanks in advance

Looks like uploader script does not see any parameters in $_GET array (GET-parameters). For example it does not see `client` and `type` ones.

Be sure you have not any network filters on your web servers or incorrect redirects (e. g. `mod_rewrite`).
