Important The new topic is not created and the profile doesn't change

At topic creation there is an empty window... And the profile doesn't change.

I think that dev's or us need to know your local system information + J! + K details before we can give any wild guess for that?

Yup your config report will help a lot

just going to go out on a limb here and ask did you read Diagnose a blank page?

I have correctly understood? Details Joomla and Kunena are necessary? (Badly I know English
)
Here everything that has found.
Joomla Ver. 1.5.23
Legacy mode:Enabled
Joomla SEF: Enabled
Joomla! SEF rewrite: Enabled
Third-party SEF components: None
Kunena 1.6.4 | 2011-05-07 | 4832 [ Kerkrade ]
Kunena template 1.6.1 |B-light |2010-11-26

Has added into components/com_kunena/kunena.php around line 25
ini_set('display_errors', 1);
error_reporting(E_ALL);

When I press "New topic" gives out an error:
Notice: unserialize() [function.unserialize]: Error at offset 73 of 325 bytes in C:\home\localhost\www\usatu\components\com_sobi2\plugins\sobisef\sobisef.class.php on line 167

[Денвер: показать возможную причину ошибки]

So you find the problem by yourself. its a sobi2 bug. please update sobi and try again.

regards 810

I have removed Sobi2, now the error isn't present, and page all the same the white

Please add the kunena report. docs.kunena.org/index.php/How_to_report_configuration_settings
