404 Page not Found TITLE translation

Hello,

Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.

Am assuming you are referencing to this support ticket. The translation here is done with WPML which is why they referenced it to be done in the settings fields. Am sure this is quite different with Loco.

Rank Math does not have control over the strings translations of your 404 page. This is done by your theme.
If you are using the latest version of the plugin, then, it would seem like a conflict with one of the plugins or the theme you are using.

To determine that, please follow this troubleshooting guide:

Only the site admin would know and your users won’t be affected by this troubleshooting.

If the issue persists, please record a video screencast using a tool like Loom showing the troubleshooting and edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

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:

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):

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

We really look forward to helping you.

Hello,

Thank you for getting back to us.

Upon checking your page I noticed that rank Math is replacing the Title tag of your header with its default “Page Not Found” tag. This is embedded within the plugin’s code but you can still translate it.

Within the Loco Translate plugin go to the Rank Math plugin and access all the strings that come with the plugin. On the search input section, you should do a quick search for Page Not Found and then perform the translation.

If this does not help you may want to try this with another translation plugin like WPML.

Else please try using this custom filter to change the 404 page not found title to your preferred translation:

add_filter( 'rank_math/frontend/title', function( $title ) {
	if(is_404()) {
    global $wp_query;
		$title = "Some Page Title Status";
	}
        return $title;
});

Make sure you change Some Page Title Status to your preferred translation and it should work fine.

Hope this is helpful. Please let us know if you have any other questions for us.
Thank you.

Hello,

Here is a workaround to which I have gone through. Rather than having this code inserted within the theme’s editor under the funtions.php, you can install the code snippets plugin and activate it on your subsite that is /cs/.

Once installed add this code within the plugin and activate it. This will only have an effect on your subsite and not the main site.

Hope this helps. Please let us know if you have any other questions.
