Problem:
The client was experiencing an issue where an anchor link on the homepage was not working correctly in the German version of the site. When clicking on the link 'Nachhaltigkeit' from any German page other than the homepage, it redirected to the English homepage instead of the German one.
Solution:
First, we suggested a series of steps to isolate the cause of the issue:
- Create a full backup of the site.
- Update any outdated plugins or themes.
- Flush any cache memory.
- Deactivate all plugins, including WPML ones.
- Activate a default WordPress theme, like Twenty Twenty.
- Activate the WPML plugins.
- Then, activate the theme and plugins one by one to find the culprit.
Additionally, we recommended increasing the WordPress memory limit to at least 128MB by adding the following code to the

wp-config.php

file:

/* Memory Limit */<br />define('WP_MEMORY_LIMIT', '128M');

Above the line /* That's all, stop editing! Happy blogging. */.
We also advised checking if the full URL was added to the anchor link and suggested using relative paths instead of absolute URLs.
Lastly, we recommended changing the language URL format to 'Different languages in directories' in WPML -> Languages, saving the changes, and re-saving the permalinks. Then, adjusting the URL in the menu item for the German version.
If you're experiencing a similar issue, we recommend trying these steps. However, the solution might be irrelevant due to being outdated or not applicable to your case.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.
