You can use the hook-code below:

add_filter( 'wpforo_auto_embed_link', '__return_false' );

Here is a helpful article: https://www.wpbeginner.com/plugins/how-to-easily-add-custom-code-in-wordpress-without-breaking-your-site/

Is there a way to disable the the auto-linking of URLs in comments? I found out, that every link within a comment automatically gets the class "wpforo-auto-embeded-link" which seems to being set by the function "wpforo_content_filter" and there this specific code within the functions.php:

if( apply_filters( 'wpforo_auto_embed_link', true, $post ) ) {
		$content = preg_replace(
			'#(|^)(https?://[^\s\'\"<>\]+)(|$)#iu',
			'$1 <a class="wpforo-auto-embeded-link" href="$2" target="_blank">$2</a> $3',
			(string) $content
		);
	}

I couldn't find an option to disable this functionality but would really like to do so.

Does anyony have any hints on this to me?

Kind regards
