CiviCRM Community Forums (archive)

I am using J1.5.26 and CiviCRM 3.4.8.

I have had a registration form working fine and suddenly 2 days ago I started getting the error below after the submit button is clicked and before the confirmation screen. Nothing has changed that I know of on the server or Joomla. Any ideas on how to fix this.  I have done some searching, but nothing has helped.  Thanks!

Error: CiviCRM-001
