Author link override affects ActivityPub plugin

[raamdev]

When Multi-Author Mode is disabled in the theme settings, the author_link is overwritten to use the home page instead of the /author/ page. This affects the ActivityPub plugin, which expects to find the /author/ link and results in the following error in Site Health:

Your author URL %s was replaced, this is often done by plugins.

We should reconsider overriding author_link altogether and instead allow this to be done in a Child Theme on a site-by-site basis.

The relevant code in the theme is here:

independent-publisher/functions.php

Lines 558 to 572 in 5b7dee7

	if ( ! function_exists( 'independent_publisher_single_author_link' ) ) :
	/**
	* Returns the author link; defaults to home page when not using multi-author mode
	*/
	function independent_publisher_single_author_link() {
	return get_home_url();
	}
	endif;
	/**
	* Changes the link around the authors name to the home page when Multi Author Mode is disabled
	*/
	if ( ! independent_publisher_is_multi_author_mode() ) {
	add_filter( 'author_link', 'independent_publisher_single_author_link', 10, 3 );
	}

Here's a quick fix that can be applied in a Child Theme to get ActivityPub working again:
