    V7 sites started erroring after security update

    Upgraded all my sites successfully the other day with the new clientdependency.dll.  Couple of days later, the V7 ones are now sitting there with the following error:-

    I've rebuilt both sites and reuploaded their dlls but the error doesn't change. Just wondering if there's a dll that needs to be set to "copy local" on my hosting. 

    Any advice appreciated.

    Hi Craig,

    From my research the root element is mssing happens when the files in the /config folder is empty, so try go make sure that these files not  are empty, And try to see this post https://our.umbraco.org/forum/umbraco-7/using-umbraco-7/52627-Umbraco-7-%28Root-element-is-missing%29?p=1 and this issue on the issue tracker http://issues.umbraco.org/issue/U4-5126

    Hope this helps,

    /Dennis

    Thanks Dennis, the config folders are populated. However, noted on one site that applications.config was 0 Bytes so reuploaded (so now 605 Bytes) and the site started working. On the other site it was trees.config that was 0 Bytes. Reuploaded (so now 6.4 KB) and the site started working.

    This is scary. Glad there's an issue raised for it.

    Thanks for pointing me in the right direction.

    Craig
