Problem: You are migrating from one server to another with the same domain and encountering a 401 error when trying to save a translation after registering the WPML plugin. Solution: 1. Ensure you have completed the migration banner at WPML > Settings by selecting that you moved the site to a new location. 2. WPML must be re-registered after every server change. Follow these steps: - Visit https://wpml.org/de/account/websites/ - If the site URL is already registered, delete it from the list. - Re-enter the site URL to create a new site key. - Click on "Show key" and copy it. - Go to Plugins > Install > Commercial (tab) and enter the key to re-register WPML. If WPML is still registered, de-register it first. If after following these steps the problem persists, we 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 the issue still remains unresolved, please open a new support ticket at WPML support forum.
