Hi,

 I need some help ASAP.

Portal has following setup:

Windows 2003 server, IIS6, SQL 2005,  DNN5.1.4 and DMX 5. I am building document management portal using DMX 5. I've added new test user to the portal and run in to trouble with the portal.  While trying to access Users in Common Tasks I got the following error:

DotNetNuke Error

 

Error An error has occurred.

Chris,

I'm not familiar with DMX from an architectural perspective but from the error message it appears to be the DMX Controller that's generating the error.  This type of error can be caused by module caching.  If the object already exists in the data cache and the module tries to dynamically add to this object you can run into this.  Go to the settings of the DMX module and make sure the cache setting is set to 0 (meaning do not cache the module).

I hope this helps,

Chuck

Hi Chris, Indeed the error originated in DMX. It was a result of adding a custom attribute with a name ("Owner") already in the main table. The architecture has been improved in the meantime to resolve this issue of name clashes. Peter
