We recently upgraded from 5.5 to 6.3 and we are now having problems creating portals from templates. When we do, we get the error below and it doesn't create the entire site. The admin link isn't even displayed. This happens if I try to create the template on either of 2 different servers and if  the portal is created on the same server the template was made or on the other server.

I've tried creating the portal with a template that does and doesn't have the data as well as with creating a new account for the portal or just using the existing one. These are sites I've created templates from in 5.5

I've seen some links on the forums about this but they seem to be old versions of DNN and say it's a bug that is fixed in version 5.x or the only solution they list is deleting modules to find the problem. We have a lot of modules and a lot of pages. Any help resolving this would be much appriciated
