@kshitij, the situation is still persists. From the error, it seems that the file was trying to save in “/” ?
I have tried other theme, it gives the same problem. As long as the custome image is uploaded, all working in perfect. Just occurs whenever I pick an image from Media Library, it will show an empty crop imange in the next step and then prompted this error after I continues to step 3.
