We're running Sitefinity 7 and I'm getting a weird error I can't seem to pin down.
When a user logs in and hits enter rather than clicking the login button, the login fails to happen and an empty error message is displayed (see attached).
This does not happen if the use clicks the login button, or if the user tries to login a second time.
Using dev tools in chrome I can see a post to /Sitefinity/Authenticate/SWT that gets canceled. (By a page reload?)
So, anyone got any ideas?
