vbulletin error

[tiburon]

I'm posting here and not on vbulletin.com 'cos I might get a quicker response.

Some users reported they are getting login timeout recently and now forgot password its not working. The email never arrives.

Didn't do any changes... updated to las 3.8 version but same problem.

Cheers
