Error: Unknown X-Auth-Key or X-Auth-Email (err code: 9103)

Hi @anotheropus,
First of all inside the plugin settings have you selected the API Key Option before providing the email id and global API Key? (Screenshot: https://i.imgur.com/WUer14a.jpeg)

Also though I personally do not use WP Rocket with this plugin and personally I don’t recommend either. But if you would like to use this plugin with WP Rocket, please check this implementation guide.

When using this plugin you need to make sure that the Cloudflare integration in WP Rocket is disabled and also WP Rocket is only being used for static file optimization and not any page caching operation.

But for just static file optimization there are many great dedicated plugins are out there. For example, you can use Perfmatter or Autoptimize for static file like CSS/JS optimization and many other WP Optimization. You can definately give Perfmatter a try.

For image optimization you can use Optimole, imagekit.io, Cloudflare Pro plan. So, many options are there. If you don’t have high traffic you can definately check out Optimole or Imagekit.io. But if you have high traffic Cloudflare Pro will be a better choice.

Thank you for the response.

I did in fact have my email ID (address) and the Global API Key added.

After many years of using W3TC for caching and going through all of the manual setups with that plugin to get a two-second page load I finally tried WP Rocket and just by installing it–without setting up any APIs or doing anything else (no instructions, no APIs, no implementation guides, etc), I got instant one-second and sub-one-second page loads. I’ve even gotten 700MS page loads with WP Rocket.

I strongly recommend it for instant, OOTB Out Of The Box fast page loads. Of course, you need to use more expensive, premium managed hosting running on NGINX servers hosted on a top-tier network, but that’s how you get speed.

After finally doing all the setups for the Super Cache plugin (using the API Token method where you must set up many new things at CloudFlare to get the token), and then disabling WP Rocket’s page caching, I got similar page loads and even slower page loads.

I deactivated and unistalled the Super Cache plugin, re-enabled all of the WP Rocket capabilities, and removed the API Token from CloudFlare. Now my site is running at and below one-second again.

I’ll stick with WP Rocket. Thank you for the support.
