[Plugin: Query Multiple Taxonomies] Reset – takes me back to the home page

I’m thinking that there has to be a way to edit the {{reset-url}} placeholder, I just haven’t found it yet.

Here’s how:

If you want to send users to a specific URL when they press the Reset button, you can do it using the 'qmt_reset_url' filter:
(ADDED TO THE THEME'S FUNCTIONS.PHP FILE)

<?php
function my_qmt_reset_url( $reset_url ) {
    return 'https://example.com/some-other-url/';
}
add_filter( 'qmt_reset_url', 'my_qmt_reset_url' );

Just make that go to your all-posts page. (which may or may not be your homepage)

That way, when you “RESET”, i.e. remove all filters, you’ll be seeing all posts.
