Support » Plugin: W3 Total Cache » Cannot Purge CloudFlare Cache: Please Enter CloudFlare e-mail

  • Hello there,

    I’m using W3 Total Cache v0.9.4.1 and WordPress 4.2.2 CloudFlare extension for W3TC is configured and enabled.

    But, even changing CloudFlare settings from W3TC (development mode, minify, Rocket Loader and Security) works, it’s impossible to Purge cache because of error

    Cannot Purge CloudFlare Cache: Please Enter CloudFlare e-mail

    This has been caused because in /wp-content/plugins/w3-total-cache/extensions/CloudFlare/general-settings-box.php file you run w3_ui_element() function to generate input fields, but for second parameter (ID) instead to provide proper id values cloudflare_email/cloudflare_key/coludflare_zone you send and these are invalid ID’s.

    Then, in file /wp-content/plugins/w3-total-cache/pub/js/options.js you have function w3tc_cloudflare_api_request() with validating that three parameters:

    var email = jQuery('#cloudflare_email');
        var key = jQuery('#cloudflare_key');
        var zone = jQuery('#cloudflare_zone');

    but as you have wrong ID’s set for inputs, this email.val() will return undefined and fail validation.

    I changed ID values to proper wording (underscore instead dot) in general-settings-box.php file and this initial validation pass, AJAX post on line #332 fails and I receive message

    Request failed. Error: unknown

    Can you please help and fix first problem with wrong ID’s in general-settings-box.php and then also see what’s wrong with that latter request.

    Thank you,

  • I have same issue. Thank Aleksandar for detailed description of issue.

    Is there any ETA on a fix for this? Is W3 Total cache looking at this at all?

    Best regards

    Same problem here.
    Any chance this could get resolved soon?


    Hi there, any update on this?
    I am getting the same error message when purging CloudFlare cache.

    Do you have any estimate when this could be solved?

    Thank you.



    Is no one fixing this? It is a glaring and obvious bug that is affecting all installations of the Cloudflare extension.

    I’ve been annoyed by this problem for well over a year now. I hope it’s fixed soon.

    I have been as well.

    This is still an issue, a year now…

    I’ve come across this issue as well. Is it safe to just change the plugin source code manually? Surely the next update will have the fix so I won’t have to worry about losing it?
