Hello @rankmath,
the second problem mentioned by @ds888 does still exist in version 1.0.54.1.
/wp-content/plugins/seo-by-rank-math/includes/modules/seo-analysis/seo-analysis-tests.php on line 55
:
'description' => sprintf( __( 'For the best SEO results, use a custom permalink structure, preferably one that includes the post title (<code>%%postname%%</code>). You can change it by navigating to <a href="%s">Settings > Permalinks</a>', 'rank-math' ), admin_url( 'options-permalink.php' ) ),
The escaping with “%%” is not working in this combination.
Thanks for a quick fix/patch!
