I can't upload an image! Error id: 2500 the reason is: S3Upload(0)

I cant upload a picture and I get this message:   id: 2500 the reason is: S3Upload(0)   how can I fix this?

I got the same error, but not always. I mean, the very same image sometimes is uploaded, and sometimes is not. Sometimes the probles dissapears after a logout and re-login, sometimes it doesn ́t. What can I do? I ́ts taking forever to finish my presentation…


i already try all the advices you gave to memo but none of them worked :confused:
