.EPS is not valid and can't be uploaded

I have been trying to upload a company logo file on a website but failed. I am required to upload an .EPS file but it is said to be not valid for print. I have no idea why is that and now I still can't upload this on the site.

The explanation of the error is below.

I have tried to upload other formats like PNG, PDF, JPEG and several others but can't go through and I still have no idea how to solve the issue.
