Upload images for product gives error message and requires log in every time

[JaloDesign]

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.

I had that happen as well a while back:

I did not do anything and after a day or so it suddenly started working again. Hope it will solve for you soon as well!
