+## [1.1.10] - 2025-12-22
+
+### Fixed
+
+- **CRITICAL:** Function redeclaration error for `wc_tpp_init()` affecting version 1.1.9
+- Fatal error "Cannot redeclare function wc_tpp_init()" when plugin file loaded multiple times
+- Plugin activation failures caused by function redeclaration
+
+### Technical Details
+
+- Wrapped `wc_tpp_init()` function in `function_exists()` check
+- Completes the fix started in v1.1.9 by protecting all global functions
+- Prevents fatal errors during WordPress plugin activation cycles
+- Both `wc_tpp_woocommerce_missing_notice()` and `wc_tpp_init()` now safely guarded
+
 ## [1.1.9] - 2025-12-22
