No (featured) images

Hi all,

I recently installed WP 3.9.1 on a new domain. But somethings going wrong with the images. I have tested this with a standard WP-theme, and only have Askimet plugin installed.

When i add a pic it doesn’t show, neither on the post on the blog itself nor in the cms (wysiwyg-view). The pic, however is in the Uploads-map, as I can see via my ftp-program.
See post Test 2 on my blog.

For the post Test 3, I tested the Featured Image-funtion. Then, the pic is showing in the post on my blog, but still not in the cms and not as a featured image.
Strangely enough, when using the Theme Simvance, you can see a featured image in the sidebar on the right, but not on the main page.

Can you help?

Best,
Edith
