Background of the issue:
I was trying to update the WPML plugin and encountered an error. To resolve it, I removed the site from my WPML account and added it again. Now, I can't register the new key. I also cannot access the WPML API-server: lien caché.
Symptoms:
I get the message 'Unable to parse data from service response.' and 'Your site can't communicate with lien caché. Code 403.'
Questions:
How can I register the new key after removing and re-adding the site?
What should I do about the 'Unable to parse data from service response' error?
How can I resolve the issue with the site not communicating with the WPML API-server?
