    Umbraco 4.11.10 YSOD in backoffce

    I get this crash on a legacy site. I'm not sure if it's just a coincidence, but that crash didnt occur in Firefox... Only Chrome.

    Hi Anthony

    Did it just happen when you logged into the backoffice? Or did you create a piece of content or upload some kind of media?

    I'm guessing that a content editor added some content at some point, then it all went belly up.
