    uSync: Error undefined - undefined

    When I try to import data from uSync I get immediately this: error

    Is there a way to know what is going wrong? Is there like a log or something?

    There should be details in the app_data/logs/ folder.

    and you can turn logging up in config/log4net.config

      <logger name="Jumoo.uSync">
        <level value="Debug" />

    But if you are using nuget make sure you have rebuilt your site after installing usync, as you can get an error like that if you don't.

    First things to look at ~/App_Data/Logs, but you're probably still in "Info" mode, so best is to change to "Debug" mode for logging (log4net.config file in ~/Config folder) and re-run the import to get more info.

    Can't garantuee you'll get more info, but it's the best you could do now

    Settings to change to get more verbose logging:

    <priority value="Info"/>


    <priority value="Debug"/>

    I seem to get this a lot as well.. even with debug turned on, I have yet to see anything containing the word "undefined" in the debug log.
