Problem: The client reported that hreflang tags were missing from the XML sitemap for product pages, product category pages, product tags, and blog post categories on their website. Solution: We recommended updating the WPML and Yoast SEO plugins to the latest versions. After updating these plugins on the client's sandbox site, we verified that the hreflang tags were correctly added to the XML sitemap. We then advised the client to update the plugins on their production site and recheck the sitemap.

Problem: The client is experiencing extremely slow loading times for sitemaps with product categories and product tags when using WPML and W3TC. Disabling WPML significantly reduces the loading time, affecting SEO performance as Google times out and fails to fetch the taxonomy sitemaps. Solution: We have resolved the issue with slow loading times in the latest version of WPML SEO, version 2.2.5. We recommend updating to this version to improve sitemap loading times.

Problem: If you're unable to see the slug translation (URL translation) in the Advanced Translation Editor (ATE) for product pages on your WooCommerce site while using WPML, but it works fine on normal pages. Solution: We recommended adding a code snippet to the site to fix the issue with percent-encoded characters in URL slugs. This solution is specifically for products that were translated automatically and removes percent-encoded characters (e.g., %80) from URL slugs during translation processing, preventing empty slugs caused by invalid UTF-8 bytes after sanitize_title() processing.
