    uSync v10 display bug

    Hi all,

    I've recently tried to upgrade uSync from v9.4.0 to v10.0.0 (I'm running the latests version of Umbraco: v10.0.1), but I keep getting a display error with every action I try to perform:

    The display error.

    In the browser console I find the following errors:

    The console errors.

    I've done some research and it seems that uSync still works perfectly fine, it's just the display that breaks. At first I thought that my NuGet package was corrupt, but even after a reinstall the error occurs.

    I'll attach my appsettings as well just in case:

    "uSync": {
        "Settings": {
            "RootFolder": "uSync/v10/",
            "DefaultSet": "Default",
            "ImportAtStartup": "None",
            "ExportAtStartup": "None",
            "ExportOnSave": "Settings",
            "UiEnabledGroups": "Settings",
            "ReportDebug": false,
            "AddOnPing": true,
            "RebuildCacheOnCompletion": false,
            "FailOnMissingParent": false,
            "CacheFolderKeys": true,
            "ShowVersionCheckWarning": true,
            "CustomMappings": {},
            "SignalRRoot": "",
            "EnableHistory": true,
            "DefaultExtension": "config",
            "ImportOnFirstBoot": false,
            "FirstBootGroup": "All"
        "Sets": {
            "Default": {
                "Enabled": true,
                "HandlerGroups": [],
                "DisabledHandlers": [],
                "HandlerDefaults": {
                    "Enabled": true,
                    "Actions": [],
                    "UseFlatStructure": true,
                    "GuidNames": false,
                    "FailOnMissingParent": false,
                    "Group": "",
                    "Settings": {}
                "Handlers": {},
                "IsSelectable": false


    I wonder what the problem could be here?

    If you have upgraded i would check there is no app_plugins/uSync folders - for v10 these folders should not exist - so if they are still on your site you will need to delete them
