And one more important thing. The Rank Math plugin you use for your SEO stops wpForo SEO and your forum SEO is now affected. Please put this code in your active theme functions.php file to fix this problem. We've added 7309 ID in the code, this is your forum page ID:

add_action( 'wp_head', function(){
	if(is_page('7309')) {
		remove_all_actions( 'rank_math/head' );
		add_action( 'wp_head', '_wp_render_title_tag', 2 );
	}
}, 1 );

@ghost,

Have you tried with a private session of browser?

Have you deleted browser cache and cookies?

We've checked and it works fine so this is your local browser or computer issue.

Please take some video and show us what happens.

@ghost,

I'm sorry but I cannot follow you. What do you mean? Could you please be more informative and follow to my instructions? As I mentioned above we don't see any issue. Have you checked it again and have you used a private session of browser to test?

You don't even take a video to show the problem, I cannot understand what is wrong on your side and what you're looking for. Your responses are a few words without any following to my questions and instructions.
