After several upgrades on one DNN installation (latest upgrade to 5.2.2) I still have a problem with Host / Extensions tab; "Object reference not set to an instance of an object."

So, my problem is that I have tab named Extension under Host menu, but can't use it (because is throwing error on opening) and tab Extensions under Admin menu, does not offer deinstallation or "Install Available Extensions" function.

Does anyone know how to fix problem with error on opening Host / Extension tab?

I suspect these identical errors are caused by permission issues:

Please verify that you both have the following set:

On your DNN web folder, sub-folders and files:

Network Service or whichever Account you're running IIS under: Everything but "Special Permissions" is selected

IIS_IUSRS:

Read & Execute
List folder contents
Read

That the above accounts have db_owner permissions on your database.

That IIS is using either the Network Service or named account that you have permissioned for your web folder and IIS.

On your DNN web folder, sub-folders and files Network Service and IIS_IUSRS have full control.

Error appeare only on Host - Extension menu (so if think it isn't permission issues).

I use a VPS with plesk and Virtuozzo, on Windows Server 2003 Standard Edition SP2 ...In the same server in a clean installation all is OK.

PS: this issue was reported in GEMINI: http://support.dotnetnuke.com/issue/ViewIssue.aspx?ID=10910&PROJID=2
