I have overwritten the wp-content\plugins\learnpress\templates\loop\course\title.php with wp-content\themes\generatepress_child\learnpress\loop\course\title.php
Please try changing the override path in your child theme to include the version directory, learnpress-v4:
Current Path (likely incorrect): wp-content/themes/generatepress_child/learnpress/loop/course/title.php
Suggested New Path: wp-content/themes/generatepress_child/learnpress-v4/loop/course/title.php
If the issue persists, could you please provide a screenshot of the exact area on the course list page where you want the custom date/time to appear? Seeing the context will help us identify the precise template file you need to override.
Let us know the result of changing the template path!
Here is an example function you can place in your child theme’s functions.php file. This code display your course start date directly below the title in the course list:
