    Login not working when using own member database

    Hi, I am having a problem with login and nForum. I've added nForum to an existing website that has it's own user database (edited web.config provider). If I use the nForum login page, I get an error (see below). If I use my own login page my website works fine, but won't browse to forum category pages (although the forum home page shows that I am logged in ok.)

    nForum login error:

    Object reference not set to an instance of an object.

    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    I am using Umbraco 4.7.0 and nForum 1.2.

    Thanks

    As its a custom integration its best to grab the source, and then debug it and step through the login and see where its causing the error.

    Hi Lee, I'm really not sure how to go about this. Are there some steps listed somewhere that I can follow? i've struggled in general to run Umbraco through VisualStudio 2010 for debugging purposes.

    cheers

    there is a video on Umbraco TV about debugging with Visual studio and Umbraco, I would highly recommend you watch it - As you create/add more packages and customise Umbraco you will need to know this in case you get more errors

    http://umbraco.com/help-and-support/video-tutorials/introduction-to-umbraco/developer-introduction/debugging?redirected=true

    I wouldn't be able to develop with Umbraco without know the above :(
