Hi,
Since two days I experience a problem uploading images. I try to upload images for cover photos. First I choose the product, then media manager, upload media, choose the image which is visible with the other earlier uploaded images. After that the screen changes with only the image I uploaded and the error message “an unknown error occured while uploading your image. Try again later.”
When I exit the media manager I get the login screen. Other functions seems to work normal.
