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

Q:

"Child theme of my weltpixel theme is not responding anymore on the edits and adjustments that we make in the admin. Can you help?"

A:

For cases like this the first thing that needs to be checked are the customizations added to the child theme as it can be a main cause for breaking theme / magento functionality. If the child theme worked ok for some time and suddenly it stopped working you may want to check the code recently added under below file:

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

A quick test to identify the root cause can be performed by switching the child theme containing customizations with the main theme, in order to bypass customizations added in wp_custom.less. 

If the store is working as expected with the main theme but failing to do so with the child theme, most probably this is caused by the code added in wp_custom.less.

Easy debugging for cases like this is to completely remove custom code from wp_custom.less and add it again section by section until you identify the code section that is breaking the theme / magento functionality.
