Problem: The client is experiencing issues with incorrect hreflang tags for languages on their website, specifically with the Norwegian language code, which is incorrectly set as 'nb-nb' instead of the standard 'no'. This issue affects the website's SEO as hreflang tags are crucial for multilingual websites to signal the language and regional URL variations to search engines. Solution: We reviewed the source code of the client's website and identified that all languages except Norwegian were using the correct hreflang tags. The Norwegian language should use the standard 'no' code instead of 'nb-nb'. If the client has created a custom Norwegian language, we recommend switching to the default language settings provided by WPML, as the custom setting conflicts with the standard language codes. To update the language codes in WPML: 1. Navigate to the WPML > Languages page. 2. Under the 'Edit Languages' section, find the incorrect 'nb-nb' entry. 3. Replace 'nb-nb' with 'no' and save the changes.
