Problem with product images upload

[fjgaspar]

Hello,

 

I have a Prestashop 1.6.0.14 webpage, and I have about one hundred products with its images in the shop. 

 

Yesterday, i wanted to record new products, and when I try to upload the product image, I got an error, without description, nor number, without clues. I tried with different images, even with images already used for other products, with no luck. In existing products, also, I can't upload any image.

 

I attach screenshots with the problem.

 

I need help, I don't have any clue about why suddenly this has stop working, and I can't continue developing my shop until this works again.

 

Thanks
