Cannot save updates to a woocommerce product with Rath Math enabled.

  • My web site is at

    Its using the Divi theme and woocommerce plus Rank Math.

    Then editing a woo product that uses the Divi editor, I see error messages when saving like this:

    Your Save Has Failed
    An error has occurred while saving your page. Various problems can cause a save to fail, such as a lack of server resources, firewall blockages, plugin conflicts or server misconfiguration…

    However, the page has actually saved.

    Disable Rank Math and the problem goes away. In not sure if this is a Divi, woo or Rank issue, so have also reported to Divi. I’m using latest version of all plugins, etc.

    Saving a normal (non product page) using Divi and Rank Math works fine. Its just when saving a product.

  • Hello,

    Thank you for contacting us and we regret the inconvenience caused.

    Could you please confirm if the following (or higher) PHP values are set?

    PHP Memory Limit: 512M
    Max input time: 150
    PHP time limit: 120
    PHP max input variables: 1000

    If not, please set the above values and see if that fixes the issue. You can also get in touch with your web host regarding this.

    Also, please confirm if you’re using any Divi templates on the product pages.

    Can you please also share the error log with us?

    Having an error log will help us determine what is causing the issue on your website.

    You can follow this guide to enable debugging in WordPress or you can get in touch with your web host, they will help you locate the log file.

    We really look forward to helping you.


    Yes all those php settings exceed those values. The only big difference is the max_input_vars: -1 which I believe means unlimited.

    There is a Divi template built using the native Divi Theme builder.

    Here the debug log:

    In this case, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

    Please do take a complete backup of your website before sharing the information with us.
