Hello. This was working before. I've J! 3.6.5 and Fabrik 3.5.2 updated today from Github. I'm trying to set a fileupload element using ajax upload. When i try to upload the picture, clicking on button Add files and the selecting the jpg file, there comes a popup with this message: HTTP Error. I'm trying to upload just one picture, I've set up on the element. What is going wrong?
