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 replacing "Add to Cart"
buttons with "View Options" links on catalog pages for products with
quantity restrictions. This prevents customers from attempting to add
restricted products directly from shop/category pages.
Changes:
- Added catalog button modification for restricted products
- Implemented "View Options" button with eye icon styling
- Created has_quantity_restriction() helper method
- Extended CSS loading to all WooCommerce pages
- Added modify_catalog_add_to_cart_button() filter method
- Updated translations with 2 new strings (en_US, de_DE, de_CH_informal)
