Full images can be viewed without problems. However thumbnails are not displayed. When I upload a picture it looks like this: When I click on Full Image it will be rendered nice in the text editor. However if I choose Thumbnail the image will be inserted like it looks here. The image links to domain.com/data/attachments/3/7651-495181523521523eac43643e564a.jpg but I dont have this image on my server. I switched servers, is there a setting I have to take care of?
