I run a few websites and recently received a report about Firefox returning a Content Encoding Error (The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression) for the first view on all pages. Once the user reloads the page, the error goes away. I'm at a loss as to what the specifics are that cause this error. I would assume it's a caching issue, as it goes away once the user reloads the page and once I flushed my full website cache, the error went away. It's back now a week later though. My website is running the latest version of Wordpress. Is there anyone who could possibly give me some guidance as to what specifically causes this issue or (even better) what steps I could take to solve it? Thanks!
