Hi I have a OAuth issue when setup MC connect.
In MC, I have already connected system API user on connector setup page.
When I try to integrate individual user, there is a error message: "There was an error communicating with Salesforce, verify your connected app is set up properly and try again." At Force.com side, there are also an error message: "Missing Consumer Key Parameter."
My package version is 5.496 (Updated 5/20/2016), there is not place to input password on MC side, I believe it's using OAuth. so do I have to input Consumer Key somewhere?
Another weird thing is that I try to disconnect system API user, also got an error : "Something went wrong while attempting to clear integration. Please try again."
So how can I solve the problem?
