Title: Interactivity API: Variation options disabled Last modified: March 30, 2026 --- # Interactivity API: Variation options disabled * Resolved [Vania](https://wordpress.org/support/users/twvania/) * (@twvania) * [1 week, 5 days ago](https://wordpress.org/support/topic/interactivity-api-variation-options-disabled/) * This issue is critical and currently blocks purchases on production stores. * There is already an open issue for this problem: [#63430](https://github.com/woocommerce/woocommerce/issues/63430), but it has been open **for over a month without a fix**, and the problem affects real stores using the `woocommerce/add-to-cart-with-options` block. * I can confirm that the issue is broader than described. * If an attribute (including taxonomy-based attributes) contains non-ASCII characters, for example: * **“Ilość”** (Polish), all variation options become disabled. Options (e.g., “ 10 ml”, “150 ml”) are rendered but cannot be selected. * From debugging, `isOptionDisabled` is triggered for all options. * **Steps to reproduce:** 1. Create a variable product 2. Use an attribute (taxonomy) named **“Ilość”** 3. Add variation values (e.g., “10 ml”, “150 ml”) 4. Generate variations and set prices 5. Open product page using `woocommerce/add-to-cart-with-options` block * **Actual result:** All variation options are disabled (unclickable): [https://prnt.sc/UkZAgS0KLXaP](https://prnt.sc/UkZAgS0KLXaP) * **Expected result:** Options should be selectable * **Note:** * This is not just about spaces — any diacritics (e.g., Polish characters like “ ść”) trigger the issue. If possible, this **needs prioritization**, as it directly prevents purchases. * Best Regards, Vania Viewing 4 replies - 1 through 4 (of 4 total) * Thread Starter [Vania](https://wordpress.org/support/users/twvania/) * (@twvania) * [1 week, 5 days ago](https://wordpress.org/support/topic/interactivity-api-variation-options-disabled/#post-18867031) * I was able to confirm that the issue is caused by character normalization. * As a quick test, I added the following workaround: * ```wp-block-code add_filter( 'woocommerce_attribute_label', function( $label, $name, $product ) { return remove_accents( $label );}, 10, 3 ); ``` * After applying this, variation options become selectable again and everything works as expected. * However, this is **not a valid solution**, since it modifies the displayed attribute labels (e.g., “Ilość” → “Ilosc”), which is not acceptable for production stores. * This confirms that the root cause is the mismatch between normalized (slugified) attribute names and human-readable labels when non-ASCII characters are involved. * Best Regards, Vania * Plugin Support [shahzeen(woo-hc)](https://wordpress.org/support/users/shahzeenfarooq/) * (@shahzeenfarooq) * [1 week, 5 days ago](https://wordpress.org/support/topic/interactivity-api-variation-options-disabled/#post-18867090) * Hi there! * Thank you for bringing this to our attention. There is already an existing issue report that occurs when the **attribute title** and **slug** are not identical. Currently, you are facing a similar issue when using specific characters like**“ ść”** in the attribute title. In this case, the slug appears as simple characters like **“sc”**, which makes the title different from the slug, as shown in this screenshot: [https://go.screenpal.com/watch/cOevosnTw6g](https://go.screenpal.com/watch/cOevosnTw6g) * Here is the bug report for the attribute title and different slug issue: [https://github.com/woocommerce/woocommerce/issues/63794](https://github.com/woocommerce/woocommerce/issues/63794) * I would suggest submitting a comment on this thread so you can receive updates directly from our developers. * I’m glad you were able to find a workaround. Please note that the issue only appears with the **Add to Cart + Options (Beta) block**. If you replace it with the **standard Add to Cart + Options block**, the issue does not occur; however, the variable will appear in a dropdown. * Thank you for your understanding and cooperation. * Plugin Contributor [Albert Juhé Lluveras](https://wordpress.org/support/users/aljullu/) * (@aljullu) * [1 week, 2 days ago](https://wordpress.org/support/topic/interactivity-api-variation-options-disabled/#post-18869499) * Thanks for opening this issue and confirming the bug, folks! A fix for it has been included in [WC 10.6.2](https://developer.woocommerce.com/2026/03/31/woocommerce-10-6-2-dot-release/). * If you encounter any issues after updating, please feel free to answer this thread or open a new one. Thanks in advance! * Plugin Support [LovingBro (woo-hc)](https://wordpress.org/support/users/lovingbro/) * (@lovingbro) * [1 week, 2 days ago](https://wordpress.org/support/topic/interactivity-api-variation-options-disabled/#post-18869652) * Hi [@twvania](https://wordpress.org/support/users/twvania/), * I can see this was a critical issue impacting purchases, so I wanted to follow up now that the thread has been marked as resolved. * Following [@aljullu](https://wordpress.org/support/users/aljullu/)’s update about the fix being included in **WooCommerce 10.6.2**, have you had a chance to update and confirm everything is working as expected on your end? * If you are all set now, that is great to hear.
