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?
