Double Base URL Problem Running Knews V1.6.3

Hi,

I searched your support forum for the solution to my problem but without any luck

am running WP 3.9.2 and K-news 1.6.3

When I try to create a newsletter (uncustomized for the time being) with sweet_bcn I get the “broken image icons”. Clicking on the header image in the newsletter shows a double base URL in the image URL after choosing a custom image.

Here are some screenshots:

This issue was supposedly solved, but I’m still dealing with it.

I’m all out of ideas. Can you please help?

Thx in advance!
Robin
