Thank you Benito, recreating the pages has resolved the problem.

The theme is based on foundationpress ( http://foundationpress.olefredrik.com ) version 2.10.4, with post content in this path: template-parts/content.php

I have created a directory MYTHEME/auto-load-next-post with the file content-alnp.php in it, with following code added:
function my_template_location() {
return ‘template-parts/’;
}
add_filter( ‘alnp_template_location’, ‘my_template_location’ );

Still doesn’t work (even withuot the my_template_location function).
Thank you for your support
