We did not find the following correspondences

Community Member

Hello all. I have been looking for similar requests on this error and did not find any. Hope this is the right place to put this. We´re trying to invite a new user from inside a course, but we keep on getting this error message: "We did not find the following correspondences", and it does not show the text box to insert the name of the new user, nothing. Even the error color is red instead of orange. 

Can anyone help me with this?
