I’ve tested this on your site, and yes it does hang, yet my account is still registered (once I refresh I can logout/login).
Can you provide more info? and I’ll try and replicate this issue locally, and find a fix.
1. It seems that your have your redirect URL in the settings set to: “http://vintagetroublemusic.com/home/”, is this correct?
2. Do you have any additional plugins (or theme settings) to manage your “coming soon” page?
