Hello,

The rank-math.php file won’t be affected by your theme or Rank Math plugin updates.

Looking forward to helping you.

Hello,

Sorry for that.

Please note that the rank-math.php file is supposed to be saved in the theme file, so any changes to our plugin shouldn’t cause the file to be deleted.

It depends on the theme if they can exclude removing any custom files within their folders so you can check that with your theme author.

We can suggest checking out different other methods on adding custom filter code to your website: https://rankmath.com/kb/wordpress-hooks-actions-filters/

We also recommend the Code snippet plugin as it ensures the code is not affected upon plugin/theme updates.

Hope that helps.

Hello,

You do not need to use the rank-math.php file when using the Code Snippet plugin.

You can use either the Code Snippet plugin or the rank-math.php to add your code snippet. Using either of them will work.

We hope that helps you.

Thank you.

Hello,

Yes, any code that works in your theme’s function.php file will also work via the Code Snippets plugin.

Just add the code and let us know if you have any issues.
