Uninstalled img upload and installed this. It doesn't work. I have Markdown installed, disabled it and enabled it again. Then I disabled all other non-vanilla extension.
The issue remains. It's the same like hcarpach
I get the following code when uploading the picture 'image 667.jpg' but there will be no picture.
