I'm trying to setup the plugin Post SMTP from wordpress.
I have a G Suite account and everything is ok, until the last step where I need to grant persmission to send the emails. I go to the page where google asks if I'm sure with the page accessing to my emails.
After I click to allow, I've got a 403 error.
Please help
It was the scope at the end of the url that google returns for granting permision, after some research I find my server has a module that doesn't allow this scopes, so you need to turn it off just to do this.
