[Zope] IOError

[Ruslan Spivak]

Hello everyone!
I'am a newbie in Zope and wrote small project - message board.
I use Zope-2.5.0 under Debian 2.2.15, MySQLdb - 0.3.5 É ZMySQLDA-2.0.5
When I go to link where my message board is located I get:


Zope has encountered an error while publishing this resource.

Error Type: IOError
