Change the read more tag in child theme

Check out https://www.ads-software.com/support/topic/removing-the-excerpt-continue-reading-link?replies=8

The goal there was to remove the link, but you can modify the last echo in function the_excerpt_max_charlength($charlength) in my last post there to spit out a permalink with whatever you want it to say. If you don’t care about the other excerpt functionality, you can strip that down to whatever you need.

Sorry but I’m still stuck ??
Probably doing something really silly…
I cant seem to get it to show my custom more tag?

function remove_excerpt_more_link() {
	remove_filter( 'get_the_excerpt', 'the_bootstrap_custom_excerpt_more' );
    remove_filter( 'excerpt_more', 'the_bootstrap_auto_excerpt_more' );
	 }
add_action( 'after_setup_theme', 'remove_excerpt_more_link' );

function spost_continue_reading_link() {
	return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'More <span class="meta-nav">&rarr;</span>', 'the-bootstrap' ) . '</a>';
}
add_filter( 'the_bootstrap_continue_reading_link', 'spost_continue_reading_link' );

I don’t have a clear understanding of exactly what’s going on, but I’ll share what I know.

In the-bootstrap, partials/content.php calls the_excerpt() to get the excerpt for an entry (but only for searches). The codex says the_excerpt will include […] but doesn’t include a read more link.

I wrote a customized partials/content.php that always called the_excerpt(). Everything I tried to remove the link was unsuccessful until I wrote my own excerpt function (see last post in thread linked earlier) and called it instead of the_excerpt(). Other people on that thread were able to get the remove filter calls to work. Your mileage may vary.

While I was experimenting with excerpts, I found that calling the_excerpt() and adding a read more link would result in a double read more link, so it seems something is going in the-bootstrap to add the read more link, but I haven’t been able to track it down. I needed to customize a copy of partials/content.php (with a different name) anyway because that’s the only way I could find to force excerpts in a list on my home page, which I want to keep reasonably short (by default, the-bootstrap only shows excerpts for searches).

Maybe there’s a better way to do it, but that’s what I found that works. Maybe post on that thread and someone there will have more help.

Thanks jmjf for your help.
I will try some of your suggestions.
