post meta issue

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.

This error in the SEO Analyzer occurs when the default table limit is already reached. However, this does not affect your site’s keywords as it is only in our internal tests’ default limits.

In this case, please add this filter on your site:

/**
 * Filter to change the Post Meta Table Limit
 */
add_filter('rank_math/seo_analysis/postmeta_table_limit', function ( $limit ) {
		return 5000000;
	}
);

And here is how to add a filter/hook to your site: https://rankmath.com/kb/wordpress-hooks-actions-filters/

Once done, clear the SEO Analyzer cache in Rank Math > Status & Tools > Database Tools > Flush SEO Analysis cache and check again.

Hope that helps.
