Instant Indexing only shows a white page

Hi @nancybaughman

A white page is most often the symptom of a fatal PHP error. You should be able to see the error details in the error log of your server, or on-page by enabling WP_DEBUG and visiting the white page again.

It is possible that the error is caused by a plugin conflict. To check that, please follow the steps in this article: https://rankmath.com/kb/check-plugin-conflicts/

Hope that helps.
