The client was experiencing a 'Too many redirects' error when accessing product URLs in secondary languages on their website. This issue occurred after updating WPML, and despite the products being untranslated, they should have redirected correctly to the default language version without errors.

We investigated the issue and found that duplicating the untranslated products resolved the redirect problem. Additionally, we applied a code snippet that helped manage product category links for translated products: <code>add_filter( \'wc_product_post_type_link_product_cat\', \'custom_modify_product_cat\', 10, 3 ); function custom_modify_product_cat( $primary_term, $terms, $post ) { if ( $post->post_type === \'product\' ) { foreach ( $terms as $term ) { $termid = apply_filters( \'wpml_object_id\', $term->term_id, $term->taxonomy, TRUE ); $term = get_term( $termid, $term->taxonomy ); return $term; } } return $primary_term; }</code> This solution might be outdated or not applicable to your specific case. We highly recommend checking related known issues at <a href=\'https://wpml.org/known-issues/\'>https://wpml.org/known-issues/</a>, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket at <a href=\'https://wpml.org/forums/forum/english-support/\'>WPML support forum</a>.

Miro	ps: Bobby, I have some good news, it seems! I have tried the proposed fix from the other thread: add_filter( 'wc_product_post_type_link_product_cat', 'custom_modify_product_cat', 10, 3 ); function custom_modify_product_cat( $primary_term, $terms, $post ) { if ( $post->post_type === 'product' ) { foreach ( $terms as $term ) { $termid = apply_filters( 'wpml_object_id', $term->term_id, $term->taxonomy, TRUE ); $term = get_term( $termid, $term->taxonomy ); return $term; } } return $primary_term; } Last time, it DID NOT work. Now it seems it does! I have tried some products BEFORE the fix: "Too many redirects." Now the same products at first display the wrong URL, but it quickly switches, does not error out and immediately redirects to the correct URL and works! Could you please confirm, too, via clicking about a dozen products (if you are able, also some older ones - they are chronologically listed and down on the page is pagination for this)? Maybe it was the latest WPML/WooCo Multilingual update that caught up to this code snippet fix? Whatever, if that is the case, I am happy beyond measure. 🙂

Miro	Hi, Bobby, sadly, we have discovered that SOME products still caused the too many redirects error. 🙁 Especially certain categories - unsure why. Everything is translated (slugs, categories etc.) properly. However, I have tried changing permalinks to much simpler ones (basically "shop URL + /product/") and this "solution", I am almost afraid to confirm (so it does not backfire again 🙂)... DOES SEEM TO WORK. We have not been able to find a product which does not work, but there are 9000 of them, so hopefully, the simpler permalinks resolved that. However for most sites this would be unrealistic due to SEO reasons, so fingers crossed the fix in the next version gets implemented. ✌️ I guess we can close this ticket. For me, the most important thing is that the site works, but of course, at a price of different permalink structure, which might be unnacceptable for others. All the same, thank you for your time and help with this, Bobby. You went out of your way to help us and I am so happy you did not merely relagate us to the docs, or make us jump through hoops. 👍
