I wrote a module and all works fine on the dev server. Now I am trying to package and install it on a different server (running the same version of DNN) and I get errors.To package the module I followed the tutorial I have found on adefwebserver. Upon installation in the event-log I get following error:

 After this I get no errors in the evenlog and everything in the module seems to work fine except for a the displaying after data has been added. No data is displayed, but I don't get errors either.

Does anyone know how to solve this?
