As recommended I upgraded to 5.1.1 on one of my sites, the day Bill Walker send a newsletter - and I run into problems in the database. It took a whole day to fix with Brians and Ales's help!
Today I would give it another chance on another of our many sites: Upgrading from 5.0.1. to 5.1.1.(All the other sites is 4.9.4, which I'm happy for).
I made a backup of the database, and I downloaded the dnn directory localt first.
When the upgrading was finish, and I go to the portal, I just se this error:
A critical error has occurred.
Object reference not set to an instance of an object.
All modules is invisible - no content?!
I restored the database whitout luck. It's the same!
What's is wrong - why is this upgrading giving so many problems - (I let my other sites be as they are, now! this is giving to many problems:O)
Can I go back to other versions - best of all 4.9.4 ?
Hope I can get help soon on this issue....
Best Regards,
