One of our paid members is unable to sign in, with the error described in this thread: Members can't sign in, "Please enter a valid email address"
The circumstances are similar: we manually added this member in the backend a few months ago, the theme is a customized version of Casper, and we recently added Portal. We haven’t made any edits to the signup file, however, and we’re currently on 3.40.5. The email address giving the error is a me.com one.
I was able to use the link generated by “Impersonate” to bypass the error, which allowed them to temporarily log in, but they are still not able to sign in via their email address.
My latest test was to delete their account in the backend and try creating a new one from the Portal signup form. That gives a different error: “Failed to sign up, please try again.” Since I also have a me.com email address, I tested my own: same error.
Any idea how to solve this?
