Commented Issue: Frontend Beta 2.0.3 [10240]

I can't add the Applications.xml file, always get this error:

Error! The requested URL returned 500 - Internal Server Error

I do not have this with the v1 frontend, and the newer one is configured the same way per the documentation.

I have solved this error. Seems the new website does not like the old Database structure. I created a new database from the 2012 Workbench. After connecting the beta frontend to the new database I am able to add the Applications xml file. Could this be due to the fact I had the old Frontend connected to this database?
