Issue with Rank Math – WooCommerce Remove Category Base causing 404 Errors

Hello,

Thank you for your query. We will be super-happy to help you with your concern.

First ensure you are using the latest version of Rank Math.

After that clear your website cache including any server-level caching services like Cloudflare. You may also head over to your WordPress Dashboard > Settings > Permalinks and click the “Save” button without changing anything.

If that doesn’t help, please get in touch with your web hosting provider and reach out to them to see if it is not a server related configuration issue.

After that, observe if you are still experiencing the 404.

If the issue persists, let us know and leave us your WP admin access in sensitive data field.

We hope that helps and we are here should you have any follow-up questions.

Hello,

The category link you have shared is still working upon checking.

We’ve seen this issue in the past where the permalinks are not sticking for more than a couple of hours, and the most common fix for this kind of issue is to refresh the permalinks programmatically.

To do that, you could add the following snippet to flush the permalinks every hour and prevent the error from appearing:

add_action('my_hourly_event', 'do_this_hourly');
 
function my_activation() {
    if ( !wp_next_scheduled( 'my_hourly_event' ) ) {
        wp_schedule_event(time(), 'hourly', 'my_hourly_event');
    }
}
 
add_action('wp', 'my_activation');
 
function do_this_hourly() {
    global $wp_rewrite;
    $wp_rewrite->flush_rules();
}

And here’s how you can add the filter to your site:

P.S. I have not yet applied the filter on your site.

Looking forward to helping you.

Thank you.

Hello,

Unfortunately, we can’t replicate the issue on our end. All the links you shared are loading fine even on an incognito window. Please see the screenshot:

Please get in touch with your web host and ask them to set at least the following values and see if that improves the situation:

Max input time: 150

If that doesn’t help, I would suggest checking with your hosting provider to investigate further.

Looking forward to helping you.
