/**
|
|
* Disable Child Theme (if Safe Mode is active)
|
|
*
|
|
* The `is_child_theme()` function returns TRUE if a child theme is active. Parent theme info can be gathered from
|
|
* the child theme's settings, so in the case of an active child theme we can capture the parent theme's info and
|
|
* temporarily push the parent theme as active (similar to how WP lets the user preview a theme before activation).
|
|
*
|
|
* @since 3.20
|
|
* @since 3.23 Moved from `ET_Core_SupportCenter::maybe_disable_child_theme()` for an improved Safe Mode experience.
