Title: Error: Cloudflare error: Missing X-Auth-Email header [403] Last modified: April 1, 2019 --- # Error: Cloudflare error: Missing X-Auth-Email header [403] * Resolved [Hrishikesh](https://wordpress.org/support/users/hrishikeshbharaligmailcom/) * (@hrishikeshbharaligmailcom) * [7 years, 1 month ago](https://wordpress.org/support/topic/error-cloudflare-error-missing-x-auth-email-header-403/) * Hi, I am using Cloudflare CDN service for my site. I am unable to connect Cloudflare with Hummingbird Plugin. When I go to Caching > Browser Caching > Cloudflare > Setup and input my email ID and Global API Key and press Connect, I get the following error message : * > Error: Cloudflare error: Missing X-Auth-Email header [403] * I have tried un-installing and fresh install of HB Plugin and also created a fresh API keys in Cloudflare, but to no avail.

Also, to avoid typos, I have copied the email ID and Global API Key from the Cloudflare account directly and pasted in the settings area. * > Could you please try and reset Hummingbird settings? You need to visit this > page to do so: wp-admin/admin.php?page=wphb&wphb-clear=all * I have done it but it didn’t work. I visited [https://thousandmilessite.in/wp-admin/admin.php?page=wphb&wphb-clear=all](https://thousandmilessite.in/wp-admin/admin.php?page=wphb&wphb-clear=all) and got redirected to [https://thousandmilessite.in/wp-admin/admin.php?page=wphb](https://thousandmilessite.in/wp-admin/admin.php?page=wphb)( i.e. Hummingbird Dashboard) * Then, I again went to Caching > Browser Caching > Configure and input Cloudflare email and API key. But still, it gave the same error * > Error: Cloudflare error: Missing X-Auth-Email header [403] * In my quest to debug this issue, I turned ON WP_DEBUG_LOG and found this PHP Warning repeated multiple times in the log: `[02-Apr-2019 05:58:40 UTC] PHP Warning: include(): Failed opening '*redacted*/public_html/wp-content/advanced- cache.php' for inclusion (include_path='.:/usr/share/php') in *redacted*/public_html/ wp-settings.php on line 84` * **Could this be a reason for the issue?** * P.S. Another strange thing I have noticed is that I’m unable to activate **Page Caching**. When I press the Activate button in Caching > Page Caching, the page simply reloads without any changes. * I have checked my WP-CONFIG file and WP_CACHE is set to true. * ``` define('WP_CACHE', true); // Added by WP Hummingbird /* That's all, stop editing!

Their API is reporting that the key/email combination is invalid. * Regarding other issues and warnings – it seems that there is no wp-content/advanced- cache.php present. You should try to disable Page Caching, remove define(‘WP_CACHE’, true) from wp-config.php and try to enable it again. Hummingbird should be able to add all configurations automatically. * Best regards, Anton * Thread Starter [Hrishikesh](https://wordpress.org/support/users/hrishikeshbharaligmailcom/) * (@hrishikeshbharaligmailcom) * [7 years, 1 month ago](https://wordpress.org/support/topic/error-cloudflare-error-missing-x-auth-email-header-403/#post-11385776) * > Regarding other issues and warnings – it seems that there is no wp-content/ > advanced-cache.php present.

It simply re-loads the page. I again checked wp-config.php and found the define(‘WP_CACHE’, true) added by Hummingbird. Also, the WP_DEBUG_LOG still shows the PHP warning : * `[03-Apr-2019 06:35:52 UTC] PHP Warning: include(): Failed opening '*redacted*/ public_html/wp-content/advanced-cache.php' for inclusion (include_path='.:/usr/ share/php') in *redacted*/public_html/wp-settings.php on line 84` - This reply was modified 7 years, 1 month ago by [Hrishikesh](https://wordpress.org/support/users/hrishikeshbharaligmailcom/).

The advanced-cache.php was missing in wp-content directory. I have manually copied from hummingbird directory. Please check & verify whether the following file permissions for advanced-cache.php is correct: - rwxrwxr– 774 File Owner (User:Group) www-data:www-data * Also, I was able to successfully connect to Cloudflare after doing this. * However, I am facing a new issue. Inside all Hummingbird Pages (in WP Dashboard), I receive the Quick Setup Pop-Up. - If I click on **Skip**, the page simply reloads and the pop-up appears again. * - If I click on **Run Performace Test**, the progress starts at 35% and remains stuck there and then, the page reloads and the Quick Setup pop-up appears again. * Please help. - This reply was modified 7 years, 1 month ago by [Hrishikesh](https://wordpress.org/support/users/hrishikeshbharaligmailcom/).
