Problem: The client was unable to see the flags in the language switcher on their website despite having them set up in the WPML settings. The issue was suspected to be caused by the Lazy Loading feature of the LiteSpeed Cache plugin, which was hiding the flags. Solution: We recommended the client to add exceptions for the flags in the LiteSpeed Cache settings. Specifically, the client should navigate to WP Admin -> LiteSpeed Cache -> Page Optimization -> Media Excludes and include the class name 'wpml-ls-flag' in the 'Lazy Load Image Class Name Excludes' option and 'switcher-language-wrapper' in the 'Lazy Load Image Parent Class Name Excludes' option. This adjustment allowed the flags to appear correctly without disabling the LiteSpeed plugin entirely.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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.
