Shop 404 permalink error

Hello,

I’m sorry to hear about the issue you’re facing with your Shop page going down intermittently due to a 404 error related to the Rank Math plugin. It’s great that you’ve already identified the plugin causing the problem.

To address the 404 error and bring your Shop page back online, you can try the following steps:

1. Flush Permalinks:

   • Navigate to your WordPress admin area and go to Settings → Permalinks.
   • Hit the "Save Changes" button once, even if you haven’t made any changes on the page. This action flushes the permalinks and can often resolve such issues.

   

2. Save Sitemap Settings:

   • Visit WP Dashboard → Rank Math SEO → Sitemap Settings.
   • Click on "Save Changes" at the bottom of the page to ensure the sitemap settings are updated.

If the issue persists after trying these steps, please let us know, and we’ll be happy to assist further.

Thank you for reaching out.

Best regards,
Rank Math Support Team

Hello,

Since the issue gets resolved when you refresh the permalink it might be that the permalinks are not sticking for more than a couple of hours and that’s why you’re facing this issue frequently.

One route to fixing this 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();
}

Here’s how you can add filter/hook to your WordPress site: https://rankmath.com/kb/wordpress-hooks-actions-filters/
