links-are-broken-404

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

In this case, we might need to take a closer look at the settings again. 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.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

https://wordpress.org/plugins/temporary-login-without-password/

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Thank you.

Hello,

When this issue happens the links are broken temporarily and then back again after re-saving the permalinks or increasing the server limits which means that the website is losing the permalink structure and their set redirections.

Currently, the categories are working on the website with our plugin enabled, but if they hit a 404 again you might need to perform a new flush of the permalinks.

To debug this issue you can install the WP Control plugin and check if there’s a scheduled action that might be triggering this.

Don’t hesitate to get in touch if you have any other questions.

Hello,

Checking your website here, currently, the category pages aren’t throwing any 404 on our end.

Once a 404 issue occurs on your end, please visit the Cron Events page right away, check the recent scheduled action and share it here so we can determine if that action may have caused the issue.

Looking forward to helping you.

Hello,

Please take a backup of your .htaccess file and replace it with the default WordPress .htaccess file. You can get the file here: https://wordpress.org/support/article/htaccess/

You can follow this guide to edit the .htaccess file:

If the 404 still persists, please contact your web host and ask them to set the following value to at least:

PHP max input variables: 1000

Let us know how that goes. Looking forward to helping you.

Hello,

Yes, that is the default .htaccess file, or you can take a backup of your .htaccess file, don’t create a new one and head over to your WordPress Dashboard > General settings > Permalink, and save the settings without changing anything. WordPress will then generate the default .htacccess.

As for the PHP max input limit, if you believe 1000 is too low for you, you can go ahead and increase that further.

See if these recommendations will resolve the issue. Let us know. We are here to help.

Thank you.

Hello,

Could you please add the following code snippet on your website to flush the permalinks automatically?

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();
}

After that, check if the pages are still getting random 404 errors with the settings from our plugin enabled.

Looking forward to hearing back from you.
