Hi, I have successfully installed WPMUDEV on several other of my sites. But when I attempt to log in after uploading and activating the plugin on I get the following error screen message.

code “rest_missing_callback_param”

message “Missing parameter(s): username, password, redirect_url”


status 400


0 “username”

1 “password”

2 “redirect_url”
