Problem: You are experiencing an issue with your WPML installation on a multisite setup where you cannot unregister the current key via the 'Unregister' button in Settings > Installer, as the site still shows that it is registered. Solution: If you're facing this issue, we recommend following these steps: 1. Ensure that the OTGS Installer is activated. According to our documentation on multisite support, you should register your main site first, which applies the same site key to all subsites. 2. To change the key, navigate to My Sites → Network Admin. 3. Attempt to unregister the site from the Network Admin area. It's important to note that you might not be able to unregister a specific site (subsite) directly.
If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your specific case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the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. Additionally, if you need further assistance, please open a new support ticket at WPML support forum.
