Hi,

I've recently installed concrete5.7.
However, when i upload images it does not show the thumbnails after upload complete. If i add an image block on a page, it links to an empty image at 1x2 px.

If i look at the cache directory, the file is there, but rather small, since it's 1x2 px.

I've tried to make images myself with GD, just to test that the installation works, and it does.

I've also enabled debugging, but no errors returned.

Any ideas?

Br,
Thomas
