I have a big problem going on right now... i just wanted to update my website and when i've tried to upload new images, nothing happens; the thumbnail shows a small icon but i can't see the image. I've tried using chrome, safari, different formats (gifs, png, jpg) but nothing. I also contacted to my website host to figure out if my storage is full, but it's not. Please, could you check this out? I have some things that I need to update!
