Why do I get a “Unable to make Cloudflare API request” error with W3TC?
Overview
The “Unable to make Cloudflare API request” error generally occurs in two circumstances:
1. A temporary issue between W3TC and Cloudflare. Please try again later.
2. The email address and API key you have added in the W3TC plugin do not match what you have in your Cloudflare account. Please make sure that both of these items are added properly in the W3TC plugin.
