Problem uploading images

Good afternoon,

Since a few weeks ago, I am having problems uploading images for the news of my Drupal7 website.

From one day to the next the images that I upload to the page in the news stopped working, they just don’t appear. I can only set pictures that were uploaded before this problem. However if I try to create a poster in left-col with the same one actually works. I have not changed the way I did it normally and I didn’t touch any adjustments.

Attached two images to see it better.

Only local images are allowed.

(As you can see here, I can preview them but then the error icon appears, so it does not appear on the page but I can still create a poster with this.)

Thanks. I appreciate your help since I have been looking for a solution for a few weeks and I have not been able.
