# Child Theme options not working / not applied -  Theme or Customizations issue (wp_custom.less)?

We sometimes hear from users who notice that their **Pearl Theme child theme** stops responding to edits or admin adjustments. If this happens to you, here’s how to troubleshoot it.

---

## First Check: Child Theme Customizations

The most common cause of this issue is **custom code in the child theme**. If your child theme was working fine before and suddenly stopped, you’ll want to review any recent changes in the following file:

`app/design/frontend/Pearl/weltpixel_custom/web/css/source/wp_custom.less`

---

### Quick Test

To confirm whether the issue is caused by your customizations:  

1. **Switch from the child theme back to the main Pearl Theme**.  
2. Reload your storefront.  

- If the store works correctly with the main theme but fails with the child theme, it’s very likely the culprit is code inside `wp_custom.less`.

---

### Debugging

The simplest way to debug is:  

1. Remove all custom code from `wp_custom.less`.  
2. Add it back **section by section**, testing the store each time.  
3. Identify the exact snippet causing the breakage and fix or remove it.

## If That Doesn’t Solve It

There are a couple of other scenarios to check:

1. **Multiple Store-Views Configuration**  
   If you’re running multiple store views, make sure the Pearl Theme is configured properly.  
   See: [How to configure the Pearl Theme when using multiple store-views](https://help.weltpixel.com/en/article/how-to-reindex-your-magento-2-store-from-admin-or-ssh-cli-1lr0qy8/)

2. **Production Mode Styles Not Applied**  
   Sometimes styles fail to apply after switching Magento to Production Mode.  
   See: [Pearl Theme styles not applied or design issues after switching Magento to Production Mode](https://help.weltpixel.com/en/article/child-theme-options-not-working-not-applied-theme-or-customizations-issue-wpcustomless-12rcc1u/)

By going through these steps, you should be able to pinpoint whether the issue comes from your **custom LESS code** or a **Magento configuration scenario**.
