[Phpgroupware-users] problem with mail module

[Ruben Lopez]

Hello,

I have installed Red Hat 7.2 with 2.4.7-10 kernel
version, phpgroupware version 0.9.12, and here is my
problem.

I\'m working with postgres on phpgroupware, and the mail
module can\'t send any mail. It\'s shows me the next
error:

--------------------------------------------------------

Warning: Variable passed to each() is not an array or
object in
/var/www/html/phpgroupware/email/inc/class.msg_imap.inc.php
on line 210

Your message could not be sent!
The mail server returned:
err_code: \'\';
err_msg: \'\';
err_desc: \'\'.

Fatal error: Call to undefined function:
parse_navbar_end() in
/var/www/html/phpgroupware/phpgwapi/inc/footer.inc.php
on line 44.
--------------------------------------------------------

Does any body know how to make it work?
Thanks for any help.

Ruben Lopez.
