Hello, How to fix the double title issue on my website (https://vevisto.com/) for each page and post.
I'm using Oxygen builder with RankMath. You can also check double title by View page source.

Please add the following code to the Code Snippets plugin:

add_action('wp_head', function() {
	remove_action('wp_head', '_block_template_render_title_tag', 1);
	remove_action('wp_head', '_block_template_viewport_meta_tag', 0);
}, PHP_INT_MIN);

Will it be resolved in 3.9 beta?
