Update: We are still working on a resolution: This appears to be sporadically impacting users that are creating their Practice Lab Account.
Scenario: Adding a New Preparer and clicking Continue after entering the applicable information. The application takes longer than normal to load and renders a server error. Once the error is rendered, the user name is not visible to the site administrator and the site administrator cannot create another user with the same username.
Impact: We have received two instances of this at two sites this morning. However, we are seeing users being created at other sites.
Resolution: This has been escalated to our development team and they are reviewing the error logs.
