I upgraded from VTigerCRM 5.04 to VTigerCRM 5.10rc and got this error after logging out and logging back in for the first time.
Mysql error: Duplicate entry ’0′ for key 1
If you are experiencing the same error, you can spend 48 hours working on it like I did or you can donate $10 to me and I’ll call you and tell you what to do. The donate button is below. I’ll get an email from paypal after you’ve sent the donation, and I’ll respond ASAP.
Thank you,
