    Blank update screen after upgrading

    Hey I was trying to update a website from V7.13.1 to V7.15.7

    after updating the NuGet package and merging the config files.

    when I start the website I get the authentication screen for like a second and it gets redirected a few times to a blank page.

    any idea how to solves this and get the upgrade screen.

    please and thank you!a screen shot of the blank page

    Hi In your web.config file, in the umbraco location near the bottom. Try adding this:

    <httpErrors errorMode="Custom" existingResponse="PassThrough" />

    When it is with the rest of the location block it will look like this:

    <location path="umbraco">
            <urlCompression doStaticCompression="false" doDynamicCompression="false" dynamicCompressionBeforeCache="false" />
            <httpErrors errorMode="Custom" existingResponse="PassThrough" />

    I hope that works for you.
