2. After install and switch your site to use Jobmonster child theme. you will see child theme folder on your site folder at 'wp-content/themes/noo-jobmonster-child'
3. If you want edit file 'jobs, companies'.
- Edit job pages: Copy file 'wp-content/themes/job-monster/archive-noo_job.php' Paste to 'wp-content/themes/noo-jobmonster-child/archive-noo_job.php' Then you can edit file 'wp-content/themes/noo-jobmonster-child/archive-noo_job.php'
- Edit companies pages: Copy file 'wp-content/themes/job-monster/archive-noo_company.php' Paste to 'wp-content/themes/noo-jobmonster-child/archive-noo_company.php' Then you can edit file 'wp-content/themes/noo-jobmonster-child/archive-noo_company.php'
Because the Jobmonster not support edit 'jobs, companies' via page builder, so, if you want edit it, you need edit it in file on child theme.
