Image Trace not working....Status Code 403

When I go to upload an image i get this message…

Status code: 403
This action has been secured by the developer of this website. Error: The signature has expired

anyone know what this is…I use this feature all of the time…kinda renders a lot of what i’m doing useless without it…

403 is a ‘Forbidden’ error. Something is blocking your access.
Are you pulling an image of your computer or using a URL to hotlink an image? (I would suggest trying the former)
