I have a brand new WP page. http://www.expatdad.ch. I already use WP for two other pages with no problems (but with a different host). On the new install, I immediately had problems with images. Thumbnails did not show, uploads for image header didn't show, etc. so after a bunch of fiddling I decided to start over.
So I created a new DB on my server, uninstalled and then reinstalled, and whoop, I have the same problems:
1) when inserting images to blog posts they do not show up, yet the image clearly uploaded as when you go to media library the filename is listed (not the thumbnail) and you can see the image when you click "edit".
2) when inserting image to header, it does not show up nor allow cropping, yet the image also is listed in the media library and can also be seen when you click "edit".
I'm assuming I probably have to contact my provider to see if there is some setting I'm missing, but if anyone has ideas before I do that, I'd be grateful.
