Problem: You are trying to set up hreflang on your site using WPML and RankMath for SEO, but hreflang is missing from all pages. Solution: If you're experiencing this issue, we recommend you try the following steps: 1. Navigate to WPML >> Languages. 2. Enable the "Display alternative languages in the HEAD section." 3. Press the Save button. 4. Clear all sorts of site/server/CDN cache and check if this resolves the issue.
If this solution does not apply to your case, or if it seems outdated, please check the related known issues, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins. We highly recommend opening a new support ticket if the problem persists. You can do so at WPML support forum.
