Question Class 'PHPMailer' not found in libraries/joomla/mail/mail.php on line 28

All of a sudden when somebody tries to post they get a 505 error
here is the message. I am using 1.7.1

Hello,

What Joomla! version are-you using ?

1.5.25

The error indicates an issue with Joomla mail. It would help to see your configuration report and also see the Global Settings in Joomla for mail.

Try changing the Kunena mail address to the same as the Joomla site mail address.

Still having that issue....

here is the config report...thanks for helping

Third-party components: CommunityBuilder 1.2.3 | UddeIm: The file doesn't exist Array.xml !

Third-party SEF components: None

Plugins: System - Mootools Upgrade: Enabled | System - Mootools12: Disabled

Modules: Kunena Latest 1.6.0-RC2 | Kunena Stats 1.6.0-RC2

Wrong versions of CB, Kunena Latest, Kunena Stats and, possibly, uddeIM used with that version of Kunena.

Please do not post the config. report as a text file. We can't read it like that. The config. report writer creates BBcode that can only be seen as a message posted on the forum. Thank you.

You have conflicting Joomla menu items. These are causing the 505 error. Simplify your menu: read How do I restore my Kunena menu? for further details.

Please attend to the matters I've mentioned here, let us know if your problems are fixed and, if necessary, post an updated configuration report.
