    Trouble creating topics in live site

    Hi,

    I have a very strange problem with my nForum installation. Everything works perfectly in the dev and staging environment, but live behaves differently. In live I can create one topic after an app pool restart without problems, but he second topic fails when updating the document cache after creating the inital post. The exception I get is:

    <error><![CDATA[MESSAGE:
    Exception has been thrown by the target of an invocation.

    STACKTRACE:

    I have been checking the differences between live and dev numerous times and can't find any significant differences. I have also copied DB from live to dev. I have made a few modifications in the nForum code for customer specific features. Most significantly I have added one field in topic and post, but everything works in dev and staging.

    I am running umbraco 4.9.0 and nForum 1.6

    Any suggestions on how to proceed are very welcome

    /Carsten

    For now the problem has been solved by inserting a small delay between creation of topic and initial post. Not a good solution though!
