I see. Why do you think it might be a database issue? This is possible but unlikely, as the front-end form does not really depend on the database.
More importantly:
1. Are there any errors in your JavaScript Console?
2. Can you check the network tab in your browser to see if any connections fail, or if some assets are not loaded?
3. Alternatively, perhaps you could provide me with a regular user account so I can login and have a look at the above things?
