**CRITICAL FIX:** Restored plugin to working state after v1.1.8-1.1.13 were completely non-functional.
**Root Cause:**
- v1.1.8 moved class instantiation from individual files to init_classes() method
- v1.1.13 wrapped classes in class_exists() guards
- Combination prevented any classes from being instantiated
- Result: No settings, no frontend, no backend functionality
**Solution:**
- Reverted to v1.1.2 pattern (last working version)
- Each class file now instantiates itself with `new ClassName();`
- Removed init_classes() method and woocommerce_loaded hook
- All class_exists() guards remain for redeclaration protection
**What Now Works:**
✅ WooCommerce Settings → Tier & Package Prices tab
✅ Product edit pages show tier/package pricing meta boxes
✅ Frontend displays pricing tables on product pages
✅ Cart applies tier/package pricing correctly
✅ All plugin functionality fully operational
**Files Modified:**
- includes/class-wc-tpp-admin.php
- includes/class-wc-tpp-product-meta.php
- includes/class-wc-tpp-frontend.php
- includes/class-wc-tpp-cart.php
- wc-tier-and-package-prices.php (removed init_classes)

Fixed critical bug that prevented plugin activation in v1.1.3, v1.1.4, and v1.1.5.
Root Cause:
- WC_TPP_Cart and WC_TPP_Frontend classes were instantiated immediately when
their files were loaded (via `new ClassName();` at bottom of files)
- This happened BEFORE WooCommerce was fully loaded
- Hook registration attempted to access WooCommerce functions before they existed
- Result: Fatal error during plugin activation
Solution:
- Removed immediate instantiation from class-wc-tpp-cart.php (line 251)
- Removed immediate instantiation from class-wc-tpp-frontend.php (line 186)
- Added init_classes() method to main plugin class
- Classes now instantiated via woocommerce_loaded hook
- Ensures WooCommerce is fully initialized before any hooks are registered
Changes:
- includes/class-wc-tpp-cart.php - Removed `new WC_TPP_Cart();`
- includes/class-wc-tpp-frontend.php - Removed `new WC_TPP_Frontend();`
- wc-tier-and-package-prices.php - Added init_classes() and woocommerce_loaded hook
- CHANGELOG.md - Added v1.1.6 section
- composer.json - Version 1.1.6
- All translation files updated to 1.1.6
- All .mo files recompiled
This fix ensures proper WordPress plugin lifecycle:
1. Plugin file loaded
2. Classes defined (but not instantiated)
3. WooCommerce loads
4. woocommerce_loaded hook fires
5. Classes instantiated with full WooCommerce availability

CRITICAL FIX: Resolved fatal error that prevented plugin activation in
versions 1.1.3 and 1.1.4. The add_cart_quantity_css() method was attempting
to access WooCommerce cart object during wp_head action, causing failures
when WooCommerce wasn't fully initialized or on admin pages.
Fixes:
- Plugin activation error in v1.1.3 and v1.1.4
- Fatal error when WooCommerce cart object not available
- Frontend errors on admin pages
- Issues during plugin initialization
Technical Changes:
- Added function_exists('WC') check before accessing WooCommerce
- Added is_admin() check to prevent CSS injection on admin pages
- Enhanced add_cart_quantity_css() with proper guards
- Line 191: if (!function_exists('WC') || !WC()->cart || is_admin())
Root Cause:
The add_cart_quantity_css() method (added in v1.1.3) hooks into wp_head
but didn't properly check if WooCommerce cart was available, causing
errors during plugin activation and on admin pages.
Updated Files:
- includes/class-wc-tpp-cart.php (enhanced error checking)
- wc-tier-and-package-prices.php (version 1.1.5)
- composer.json (version 1.1.5)
- CHANGELOG.md (v1.1.5 section)
- All translation files (.pot, .po, .mo) updated to version 1.1.5

Enhanced package quantity restriction enforcement by hiding the cart
quantity input field when restrictions are enabled. This prevents
customers from modifying quantities in the cart to bypass package
restrictions.
Changes:
- Added cart quantity input hiding for restricted products
- Implemented woocommerce_cart_item_quantity filter hook
- Created maybe_hide_cart_quantity_input() method in WC_TPP_Cart
- Fixed cart quantity bypass vulnerability
- Cart displays quantity as read-only text for restricted products
