Problem:
You are experiencing issues with WPML's AI Auto Translate feature not working, encountering an API error stating 'No sitekey found for this website', and translations are stuck in the queue.
Solution:
First, ensure that you have the correct sitekey configured for your website as it is essential for the AI Auto Translate feature to function properly. If you are unsure about how to check or update your sitekey, please refer to our documentation here: WPML Documentation.
Additionally, we have recently updated our AI Auto Translate feature to support new language pairs such as Dutch to English and French. We recommend trying this updated feature to see if it resolves your issue.
If the problem persists or the solution provided here is not relevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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.
