Double <title> Tag with SEO Plugins in WordPress 5.8

[katsar0v]

Hello,

I updated to WordPress 5.8 and am using RankMath. However I noticed there are two viewport tags as well two <title> tags. I guess the code in wp-includes/block-template.php:86-88 has something to do with it. I would very like to get rid of the second <title> tag not belonging to the seo plugin.

I am also using the Oxygen Builder (3.8.1) if that helps.

Hi @katsar0v, Thanks for the ticket.

Is this issue reproducible with one of the default themes and with all plugins disabled? If not, then it seems like something you should report to rankmath or the plugin/theme that may be responsible.

Hello @jorbin, I decided to open this ticket because I saw on the code that WordPress enforces viewport and title which I can only remove with this snippet:

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);

@katsar0v Talked with the Rank Math team and they reproduce this issue with Oxygen Builder. And this issue is happening with other plugins too. Deactivate all the plugins and check as @katsar0v suggested.

Thank you

It looks for me like a general issue

$template = locate_block_template( $template, $type, $templates );

enforces wp-includes/block-template.php which by enforces the viewport and title tags.
