Doteraz mi pri pár cvičných inštaláciách plugin fungoval bez problémov a zrazu nechodí. Napísal som pani autorke, do 24 hodín som mal odpoveď – naozaj je potrebné stránku pokladne Checkout vytvoriť pomocou starého shortkódu [woocommerce_checkout] …a potom to funguje s témou Sydney perfektne.Vďaka za čas, ktorý pluginu venujete, pani Vyskočilová.

Useful for non-profit organizations where IČ DPH does not match SK” + DIČ. Go to WooCommerce > Settings > General > Kybernaut IČO DIČ options. #### 1.10.4 (2026-03-19) * Fix: VAT exemption not applied when Buying as a company” toggle is disabled. When the toggle was off (fields always visible), the VAT exempt check silently failed because it required a non-existent checkbox to be checked. #### 1.10.3 (2026-03-18) * Fix: Trying to access array offset on null” error on checkout when `shipping_country` or `ship_to_different_address` POST fields are not set (e.g. when shipping to billing address). * Fix: Added missing `isset()` checks in VAT exempt validation for parsed POST data. #### 1.10.2 (2025-11-28) * Fix: Don’t autofill DIC (Tax ID) for companies with terminated VAT registration(` ZANIKLY`). The plugin now checks VAT registration status from ARES and only autofills DIC when the status is `AKTIVNI` (active). See [support forum](https://wordpress.org/support/topic/dic-v-pripade-zanikle-registrace-k-dph/). #### 1.10.1 (2025-05-13) * Added a new filter `woolab_icdic_enable_dic_dicdph_match_check` to disable the DIČ and IČ DPH match validation. For more details, see the [support thread](https://wordpress.org/support/topic/ic-dph-validacia/#post-18440969). #### 1.10.0 (2025-04-24) * Performance improvement: function donetyping is replaced by debounce function by [@morvy](https://github.com/morvy), [#74](https://github.com/vyskoczilova/kybernaut-ic-dic/pull/74) fixing issue [#73](https://github.com/vyskoczilova/kybernaut-ic-dic/issues/73) * Fix: Shipping country and VAT country prefix must match (paid by a supporter)( before only billing & VAT number matched). * Feature: Add basic logger. #### 1.9.1 (2024-11-14) * Fix: Greek VAT number validation – VAT country prefix (EL) doesn’t match WooCommerce coutry code (GR). #### 1.9.0 (2024-06-28) * Feature: New checkbox Ignore when ARES or VIES check fails for technical reasons” in plugin settings. If this option is enabled and validation of business ID or VAT number fails for technical reason (not because it is invalid), an order is placed. For orders at which validation fails, there is an alert at admin edit screen and in admin e-mail.
