Problem: You are trying to add the site key in the OTGS installer but cannot register the key. Solution: If you're experiencing this issue, we recommend you first go to your WPML.org account profile and remove the key generated for the site you are attempting to register. Then, navigate to Plugins->Add new->Commercial tab in your WordPress admin. Here, either unregister WPML or register WPML and click on "Get a key for this site". This action will automatically generate a new key code for your site.
Please note that this solution might be irrelevant if it's outdated or not applicable to your case.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 the issue persists, please open a new support ticket.
