I'm trying to upgrade umbraco 7.1 to 7.3 in Visual Studio 2012. I updated via NuGet and when I view in Google Chrome i'm getting to this url umbraco/AuthorizeUpgrade?redir=%2finstall%2f%3fredir%3dtrue%26url%3dhttp%253a%252f%252flocalhost%253a50333%252f
and the page is blank with no error message (i can see a black background with the Umbraco logo).
Any help with this issue?
I did the hard cache clear and i'm getting a lot of js errors
It might be worth looking at this post which should hopefully resolve your issue.
Chrome could also be the culprit as it heavily caches. Also worth clearing the cookies and clearing out the cache.
Thanks for the refering link. I think I made some progress. I did check the webconfig and umbraco dll versions. They do match now.
I have the following js errors.....could that be why my issue persists?
Edit to add: I have cleared all caches and even viewed in a brand new browser (IE), but the same issue is occurring.
Did you manage to solve this?
I have the same problem upgrading from 7.3.1 to 7.4.0 using NuGet.
My web.config looks like this:
<add key="umbracoConfigurationStatus" value="7.4.0" />
<compilation defaultLanguage="c#" batch="false" targetFramework="4.5" debug="true">
My umbraco.dll and Umbraco.Core.Dll are both 7.4.0.
Edit: 15 feb 2016:
Using either Edge browser Developer Tools or Firefox 44.0.2 the Network log shows 404 for the following files:
This is what I have tried but still the problem persists:
It makes sense to me that the AuthorizeUpgrade page is blank when AngularJs and the other js file are not loaded but how can this be solved?

This issue is reported here: http://issues.umbraco.org/issue/U4-7955
Any help is appreciated.
For others having this problem I managed to fix it:
It turns out some files were missing and some outdated in the /Umbraco folder. I ended up deleting the old /Umbraco folder and replaced this with a fresh copy from the offical umbraco zip file. Problem solved.
Apparently NuGet upgrade does not always work perfectly.
Same problem, same fix. Download, unzip, overwrite Umbraco folder and we're back up & running! Thanks!!
Thanks for posting this, it helped me get past this issue.
Old post but I just had this issue as well. The problem was that the new files in the umbraco folder from the new version was not included in the csproj-file in visual studio. This caused issues on the buildserver/deploy but worked locally.
is working on a reply...
