Found it! atomic-paging-nav in Template Tags php
changed “posts” to “articles”
😀
One question — I have created a child theme and put all my changes in that folder in order to leave the originals intact. One problem I have run into is that the Template-tags.php file is in a subfolder — when I move it to the child root directory or create an inc subfolder in the child it is not recognized — I have made the modifications in the original file for now but would prefer to do it in the child. I’ve Googled it like crazy and this seems to be a problem for others (using different themes) as well. Any thoughts on this? Thanks.
template-tags.php must be correctly referenced in functions.php , line 148:
/**
* Custom template tags for this theme.
*/
require get_template_directory() . '/inc/template-tags.php';
It is also referenced in languages/atomic.pot from lines 331 through 337.
