How get details of unexpected sharepoint error?

Question

I have deployed sharepoint solutions. Some of web-parts always cause unexpected error. Some days ago they worked, before installing sharepoint on new server.

I will try to find error details.

• In Central Administration http://localhost:3442/_admin/metrics.aspx in Trace Log C:\program files\common files\Microsoft shared\Web server extensions\12\LOGS files have not detail.aspx information.
• IIS logs is not contain useful information too
• Windows Event Log is empty
• I switched <customErrors mode="Off" /> in all .config files.

How I can solve this problem? How I can to find details of the error?

For switch off sharepoint error handler you must to change web.config so as following example

<configuration>
<SharePoint>
    <SafeMode MaxControls="200" CallStack="True" DirectFileDependencies="10" 
     TotalFileDependencies="50" AllowPageLevelTrace="True">
