Problem: The client was experiencing issues with non-functioning URLs on their multilingual website. They suspected that WPML was not working correctly despite being up-to-date. Additionally, the WPML CMS plugin did not appear in the Plugins page after installation, and the client continued to see messages indicating that it should be installed. Solution: We installed the core WPML plugin for the client. The issue was that the plugin package was incomplete, which prevented it from appearing in the plugin overview and functioning properly. After the correct installation, the .nl subdomain became accessible, and the 404 errors, likely caused by the plugin's previous deactivation, were resolved.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we recommend opening a new support ticket.
