Support » Plugin: Smush Image Compression and Optimization » Content Encoding Error while bulk smushing

  • Resolved marcomancosu



    I just installed and activated the plugin, but when I bulk smush the images I keep getting an error message:

    Content Encoding Error. The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

    I click on Try again and the plugin keeps working on the images. The error occurs every few images. I have hundreds of pics in my website so it’s probably going to take a very long time to bulk smush all of them.
    Do you know why I get this message and what I should do to avoid it?
    if you need the website:

    Hi @marcomancosu

    It might be best to disable the compression(Settings > and then upload all your images and bulk smush them from the media manager.

    Let me know how you get on please.


    Hey there.

    We haven’t heard from you in awhile, so I just wanted to check in to make sure all was good.

    This thread was marked resolved, but please, if you still need help then just respond and open it back up. We can then take it from there. 🙂

    Hope you have a fantastic day!
