Let me guess – when you’re logged in, your website loads just fine, but when you log out and reload your website, it looks like a wall of gibberish? That’s due to overlapping compression, most likely between your cPanel’s zlib compression and a compression plugin on your WordPress site.
How to fix this
You’ll be surprised how easy it is to fix this. Simply:
- Login to your WordPress admin
- Enter the settings page of whatever compression plugin you’re using (e.g. I’m using Swift)
- Disable GZip
Alternatively, you can disable the one in your cPanel:
- Login to cPanel
- Enter the “Optimize Website” page
- Do not compress anything
- Enter the PHP Options
- Disable zlib_compression
Let me know if it works for you too. Alternatively if you have any other suggestions, feel free to add to comments!
