invalid_client

Hi!
The error is odd as we can clearly see it is there. Are you also sending a client in the header as well. I see there are 8 headers being sent from your screenshot provided.

Thanks

Hi,

It looks to be that permalinks may not be setup as needed in WordPress. Please either enabled permalinks by go to Settings->Permalinks.

Or, changing the URL to use ugly URLs.

Example: yourdomain.com?oauth=authorize

I has change same here: https://prnt.sc/rdo742. Code authorize don’t have only show HTML. Thanks

The URL you changed it to is not correct.

Be sure to use properly formatted GET requests.

There is too many ? symbols being used in your URL. The first ? used is the only ? used. Every parameter after that should be defined using &.

I fix “?” from redirect_uri. And this issue: https://prnt.sc/rdoa7a. Can you suggest me to fix its. Thanks
