Problem: The client reported that hreflang tags were missing from blog articles, although they were working on pages. Solution: We asked the client to ensure that the option "Display alternative languages in the HEAD section" was checked. This option can be found in the WPML -> Languages -> SEO Options section. If you're experiencing this issue, we recommend you verify this setting.
If the solution provided here is not relevant to your case, because it might be outdated or not applicable, we suggest opening a new support ticket. We also highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
