Support » Plugin: WooCommerce » In the checkout page, order summary frame shows endless loading for cached nonce

  • Resolved nic0net


    I have a problem in the checkout page of WooCommerce plugin, I prefer not to disclose the site URL unless it’s really necessary for further analysis.
    I suspect the problem being the one described in this WooCommerce documentation page, at point 3: “Invalid Response from an AJAX Call” where talks about cached nonce, quoting

    You may also see a response of -1, This is a security failure and is caused by a cached nonce.

    In fact the GET request to “https://mysite/homepage/?wc-ajax=update_order_review” gets a 403 response with “-1” as json response.

    Since the site is not already in production I switched back to twenty-sixteen theme and disabled all the plugins but WooCommerce. Then I removed all transient data and clients sessions from the WooCommerce control panel.
    Reading a bit about nonces I tried to purge the cache (if present) with a couple of plugins which I then deactivated and deleted, tried to complete the checkout from a different browser with cache disabled but this didn’t work.
    I found this discussion on the forum that is about a slightly different error but I think doesn’t apply to my situation because I don’t require authentication to complete the checkout process.
    For clarity consider that I have enabled Paypal as payment method but the issue persists even if I disable the option, with the one small difference: when Paypal is activated, inside this component: <div id="order_review" class="woocommerce-checkout-review-order"> (that shows the correct order summary information in transparency and above that the – endless – loading symbol) there is also the payment component: <div id="payment" class="woocommerce-checkout-payment" style="position: relative; zoom: 1;"> that behaves the exact same way.
    If anyone minded, I don’t use Braintree, instead I wanna point out that the website resides on a server managed by “Siteground” if may help.

    I wonder if someone could complete the documentation page cited at the beginning of the post adding further explanation on how to solve the cached nonce problem.

    I hope my explanation will help finding the solution. I will try to provide more details if needed, any help is appreciated.
    Thanks in advance.

    If your host is serving cached pages (e.g. with Varnish) this could cause the issue. When the ajax request is made there is a security nonce included with it ( This nonce is periodically expired and a new one is created. If this nonce has expired you will get the error you are seeing if you try and use it, which would happen if the host was serving cached pages. Hope this helps.

    Thanks to your suggestion I checked the configuration of the hosting server and it was serving cached pages with SuperCache so I disabled it completely. Then I made sure that W3 Total Cache plugin was disabled and tried again.

    Sadly nothing changed, the XHR request is still returning “-1”.
    Here are the request headers:

    GET /homepage/?wc-ajax=update_order_review HTTP/1.1

    Why did it do the request to /homepage/? Shouldn’t be doing the request to some woocommerce plugin page?
    Note that in the root directory the .htaccess file has this rule: “Redirect /index.html /homepage/”.

    Here are the response headers:

    Are the fields “expires” and “cache-control” (the first ones) normal? Maybe 11 Jan 1984 is a bit old, isn’t it?

    I tried to make the request also with a different browser:

    GET https://mysite/homepage/?wc-ajax=update_order_review HTTP/1.1

    Does this provide some useful information?
    Thanks for your interst.

    I confirm that, server side, Siteground’s technicians said they disabled all the caches for my site. I deleted w3 total cache plugin and disabled the other plugins. Anyway the page is still there endless loading.
    I hope that soon somebody will find out something, I can’t be the only one with this problem.
    Thanks anyway to who tried to help until now.

    Hi @nic0net

    Can you create a new install with SiteGround and install WooCommerce and activate the TwentySeventeen theme, then tell us if you have the same issue?




    I’m trying to set up another install both on localhost and with SiteGround to see where is the problem. I’ll get in touch as soon as possible.

    Do keep us updated on this please.

    I finally solved the problem, it was originated by the redirect rule in the .htaccess file under root directory: “Redirect /index.html /homepage/”.

    I’m sorry to have bothered you for a distraction like that,
    Thank you anyway.

    I’m having the exact same issue where random users keep having a white overlay on the checkout page. Can’t figure out what the problem is. Have deleted user sessions, transients, disabled all caching and turned on/off several plugins.

    When I was remote-desktopping a user that was experiencing the issue he also had the -1 returned on the pageload check.

    I can’t for the life of me figure out what is going on and how to fix this.

    Even the hosting turned off Varnisch Cache to be absolutely certain everything is generated on the get-go.

    Could you elaborate how the redirect was interfering with your nonce check?



    I had this issue, and here’s what was happening to my site. Once a customer got to the checkout page and logged in as a returning customer, spinning wheels got stuck over the credit card (Stripe) area with the same error as described by @nic0net.

    In a single site build, a solution on another thread was to remove these lines from your wp-config file:
    define( ‘ADMIN_COOKIE_PATH’, ‘/’ );
    define( ‘COOKIE_DOMAIN’, ” );
    define( ‘COOKIEPATH’, ” );
    define( ‘SITECOOKIEPATH’, ” );

    In my case, I received the checkout error on my multisite build. I need some of those lines to prevent an admin redirect loop. After some trial and error, keeping these lines solved the problem and allowed admin login:
    define(‘ADMIN_COOKIE_PATH’, ‘/’);
    define(‘COOKIE_DOMAIN’, false);
    define(‘SITECOOKIEPATH’, ”);

    Removing define(‘COOKIEPATH’, ”); makes moving from one site to another in the admin break a bit – possibly due to the domain mapping plugin is setup. Logging into a child site on another browser is my workaround until the cookie issues are sorted out.



    Regarding what happened to me I think that the Ajax request was made to the wrong page because of the redirect. As you can see my request was made to /homepage/?wc-ajax=update_order_review HTTP/1.1 but maybe should be made to /homepage/index.html?wc-ajax.... Note that there was a redirect from /index.html to /homepage.
