I try to update my wordpress but goot this error " Updating failed. The response is not a valid JSON response".
I check my /wp-json/wp/v2, and find out that it return Error 1020: Access Denied
I check my firewall, but find I was blocking thi URI.
I removed it and ad a new rule that allow http:// domain . com /wp-json/wp/v2 , the error still here.
Does anyone knows how to fix that, so I can actually update page on wordpress.
