Problem: The client reported an issue with mixed content warnings on their website using the WPML plugin. The warnings were related to HTTP resources being loaded instead of HTTPS, specifically flag icons. Solution: We discovered the issue was due to a conflict between the lazy loading script enabled in both the Theme settings and the WP Rocket plugin. To resolve this, we disabled lazy loading in both settings, then re-enabled it only in the Theme settings and resaved the permalink structure. This adjustment ensured that the flag icons loaded correctly over HTTPS without recurring issues.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we recommend opening a new support ticket. Additionally, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
