Support » Plugin: WP-Optimize - Clean, Compress, Cache. » Empty data returned by server

  • Resolved Panos Sakalakis



    I’m trying to compress the images of my blog and I am keep getting the same error over and over again:

    Empty data returned by server
    There was an error connecting to the image compression server. This could mean either the server is temporarily unavailable or there are connectivity issues with your internet connection. Please try later.


    It seems weird because the WP-Optimize works great in (which is a sub-blog) but not in the main blog

    Any ideas?

    Thank you in advance!

    Can you try selecting a few images and see it that works?

    Can you also try to temporarily deactivate the other plugins you have installed on your site?

    Do you still get the same issue?


    Hello! Sorry for the big delay. It seems that if I selected a few images and not all of them it works. Any ideas why? I have too many images to optimize and selecting a few every time takes time.
