[phpGroupWare-users] Login php errors

[Mike]

My team got to the office today to find the following errors after hitting the 
login button on our calendar

Warning: array_flip(): The argument should be an array in 
/websites/cal.domain.net/phpgwapi/inc/class.sessions.inc.php on line 644

Warning: Cannot modify header information - headers already sent by (output 
started at /websites/cal.domain.net/phpgwapi/inc/class.sessions.inc.php:644) in 
/websites/cal.domain.net/phpgwapi/inc/class.phpgw.inc.php on line 152

Nothing obvious in the apache logs. I'm searching through some google searches 
that match a similar syntax as the errors above but not really having any luck. 
I don't think anyone was tampering with it between yesterday afternoon, the 
last time it was known to work fine and this morning. Thanks for any insight 
you might be able to give me. Sent from the phpGroupWare forums @
