Support » Plugin: WooCommerce » new built-in feature to detect fatal errors

  • Resolved HollyKNY


    My customer received the following message from WordPress (pasted below with personal information removed). I have not found anything visibly wrong on the site – no error messages and functionality seems to be fine. All versions of PHP, MySQL, etc., are all current, as are the plugins, with no alerts to update anything.

    Thanks for any tips.


    Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

    In this case, WordPress caught an error with one of your plugins, WooCommerce.

    First, visit your website (SITE) and check for any visible issues. Next, visit the page where the error was caught (site/wp-login.php) and check for any visible issues.

    Please contact your host for assistance with investigating this issue further.

    If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.


    To keep your site safe, this link will expire in 1 day. Don’t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

    Hi there,

    When looking at the error in question, I noticed the following important bit:

    Out of memory

    Practically this means that amount of memory allocated to your hosting setup isn’t enough for all the data that it needs to process. To remedy that, you’ll first want to get in touch with your hosting provider as they’ll need to make some changes to your hosting setup (it’s not something you’d have direct access to from the WordPress admin area).

    Thanks for looking into this for us. I did ask the hosting company yesterday to increase the memory and they had me add this to the wp-config file. Hopefully will be enough.

    define('WP_MEMORY_LIMIT', '64M');
    define( 'WP_MAX_MEMORY_LIMIT', '128M' );

    Thanks for the update!

    You’ll want to keep an eye on the errors that your site is generating. If the “out of memory” error disappears, then increasing the memory did the trick.

    For some background information, WooCommerce recommends a minimum of 128M of memory:

    More memory can be helpful. If you’re still seeing the “out of memory” error, then you can add a little bit more memory. Alternatively, you can check to see what’s actually using the memory. Here’s a good place to get started:

    We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
