Problem Wordpress

I can’t upload media through wordpress, it keeps showing me this message error, “There’s an error in the upload, Try later”
And I don’t know whats the problem, the images aren’t that big, they not surpass the 10 MB limit, I can’t upload them through FTP either.

If anybody can help me, I’ll be grateful.

What else can you tell about the uploads? How large are the files? What kind of file type/extension do they have? To which folder are you trying to upload them? What error message do you see when trying to upload them through FTP?
