Suddenly getting error of "Value cannot be null. Parameter name: source" while login in to Umbraco. But, website is running as expected. Can anyone please help me on it. We have Umbraco v6. It's high priority issue as want to update the contents.
Are you able to check in the database your umbracoUser entry for the user you are logging in with and their corresponding details in teh
umbracoUser2App table?
(if my memory serves me correct)
Basically in Umbraco 6, the User Ids are mapped to the apps they are allowed access to, eg content, media users etc
What your error message is saying is that when Umbraco tries to get the the applications for the user you have logged in with, the cupboard is bare! and an error is thrown.
Now just recycling the app pool may make this all ok, there might be lots of reasons why GetApplications() is no longer retrieving the applications...
but it could also be somehow the mappings in that table were wiped?
