Hi,
I am using discourse WordPress plugin and it was working fine. I was able to publish posts from WP admin. Currently what happens is like when I Publish the post it throws error
There has been an error publishing your post: You are not permitted to view the requested resource. The API username or key is invalid…

I checked the API settings and username and it was fine. In order to confirm the configuration I tried curl request in postman and it returned 200 status.
Can someone help me on this?

Few days back I had upgraded the PHP version. Not sure if this has any impact on that.
