I am working on a fresh install of the most recent DNN version I downloaded from the site today. I am working on a client's site and am ready to use the custom theme I created. I have done this many, many times and use the same template as my start for dnn themes. I have been noticing that for some reason this installation has been very buggy for me.

 In particular, when I go to site settings and try to change the skin or container then click update at the bottom, rather than submitting my change request, it empties the entire form and won't submit because it says the site name is blank, when it was just filled moments before. What could be causing this bug?

I also encountered a case where I could not enter site settings or my account notifications page because of missing an authorization key. Any help in figuring this out would be greatly appreciated.

I fixed the anti-forgery token but am still having problems with the site settings. I checked the event viewer as well as the debug console in my browser and don't see dnn errors or javascript errors which is very strange. I also just tried going to my page management and changing the default skin for a page there and am getting the same problem so its nots limited to the site settings it seems. Very strange indeed.
