Hi

The installer seems to setup the appender wrong in the log4net.config. Both the appender-ref and appender tags are inserted INTO the existing tags instead og NEXT TO. See my config here:

<?xml version="1.0"?>
<log4net>
  <root>
    <priority value="Info" />
    <appender-ref ref="AsynchronousLog4NetAppender">
    <appender-ref ref="uSignalrAppender" />
    </appender-ref>
  </root>
  <!--To Change the way logging works for certain namespaces, insert a new logger like: -->
  <!--
    <logger name="Umbraco.Core">
        <level value="WARN" />
    </logger>-->
  <appender name="AsynchronousLog4NetAppender" type="Umbraco.Core.Logging.AsynchronousRollingFileAppender, Umbraco.Core">
    <file value="App_Data\Logs\UmbracoTraceLog.txt" />
    <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    <appendToFile value="true" />
    <rollingStyle value="Date" />
    <maximumFileSize value="5MB" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
    </layout>
    <appender name="uSignalrAppender" type="USignalrLog4net.SignalrAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date %-5level - %message%newline" />
      </layout>
    </appender>
  </appender>
</log4net>

This prevents logging to signalr
