Problem: You are experiencing an issue where switching languages directly from the homepage results in an incorrect URL format, specifically adding an extra underscore (e.g., '.it__/?lang=en' instead of '.it/?lang=en'). This problem does not occur when switching languages from another page and then returning to the homepage. Solution: We recommend the following steps to resolve this issue: 1. Ensure all plugins, including the WPML suite, are updated to the latest versions. 2. Remove any unused plugins and clear all caches. 3. Refresh permalinks through Settings → Permalinks in your WordPress dashboard. 4. Re-test the homepage language switch. If these steps do not resolve the issue, it may require a manual inspection of the site and server URL rewrite rules, specifically for the homepage. Additionally, review the WPML language switcher settings and homepage permalink structure, and check for any custom functions or hardcoded URLs in the homepage template.
If the problem persists or the solution seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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. If needed, please open a new support ticket at WPML support forum for further assistance.
