Ckeditor design templates - Blank overlay

[glennb]

Hi Guy

For my project, I need my user to have the ability to insert page design templates from the ckeditor toolbar.
So I changed the gsconfig.php file and it all pop's up fine en smoothly.
Although, when I select the 'Templates'-button, I only get a white overlay... showing... nothing.

I have been looking around, but I can't seem to find a quick fix or solution.

Thanks in advance.
