Symptoms:

Questions:

Thank you for contacting WPML Support and for sharing the screenshot and details. Sometimes, these messages can be false positives that get stuck, and you can verify this by following the steps below:
1. Please attempt to remove the warning message by clicking the small 'x' icon on the message.
2. Afterward, refresh the dashboard to check if the warning message persists.
If the message disappears, then everything should be in order. However, if the issue persists, please inform me so that we can further address it.
