Background of the issue:
I am trying to complete step 4 of AI TRANSLATION using the WPML plugin. The issue can be seen on this page: الرابط المخفي.
Symptoms:
I encountered a 403 forbidden error with the message 'Api authentication error invalid signature'. The console shows a reload page with the error: {"errors":[{"status":403,"title":"Api authentication error invalid signature","detail":"The signature is invalid"}],"success":false,"error":{"class":"ApiAuthenticationError::InvalidSignature","message":"The signature is invalid","backtrace":null,"cause":null},"status":403,"explanation":null}.
Questions:
Why am I receiving an 'Api authentication error invalid signature' when trying to complete step 4 of AI TRANSLATION?
How can I resolve the 403 forbidden error to proceed to the next step?
