Object reference not set to an instance of an object.

- Used the install package instead of the upgrade because had still some issues remaining from a previous 3.x to 4.4.0 upgrade path and wanted as much as possible a refresh of the code (??).  Issues outstanding (are posted on the forum but never got solved) 1. not being able to use the default skins - garbage text in the header of the default skin - as an intermediate solution installed Dynnamite free skin and this worked fine 2. File manager sync problems

- copied connection strings and machine & validation key to the web.config in the install package.  Uploaded everything to the website.  Upgrade process ran without errors.

- as mentioned was using DyNNamite free skin because of problems with the default skin.  In the mean time went into the database (Skins table) and changed the DNN instance to use the default skin (corrected the path) but still the same problem.

Did I do something wrong ?  Should I have taken the upgrade package ??

THx very much for your help

DIRK

The Machinekey and decryptionkey are correctly transferred to the new web.config

Am really out of options here.  Run several DNN installations at several host companies and never had any problems like this.  have already done plenty of upgrades.

Only log file containing something was also from previous upgrade - 4.3.6.log :
