Hi all,

I've run into this problem before but none of the old tricks works. Problem is that my newly upgraded (3.06 to 4.02.1) Umbraco solution just doesnt open the subtree below Packages in the developer section.

Everthing else seems fine.

I've checked that website has the right folder permissions. All is ok (currently it's with full access to all folders)
I've doublechecked that under data/packages exists 2 folders: created and installed each containing one configfile. Both are fresh copies.

I've found the following in the Application Events:
