    Hassan, peace be upon those who follow guidance.

    You mentioned that you use Umbraco V8 and the starterkit package you tested I don't see it available in the V8 also in the package page shows older files.

    enter image description here enter image description here

    I suggest that you connect to the backoffice and uninstall the package.


    Umbraco moved to V8 and many changes made to the core which means that package created for V7 may needs changes and new release for V8.

    In case you want a starterkit to work with and navigate the CMS try to connect the backoffice, install a starterkit from there or install it manually after checking the zip you downloaded is compatible with V8.

    Hi Tarik.

    Many thanks. I knew what I was doing is stupid. Anyway, I am not able even to connect to the backoffice. Any suggestion?

    I tried to restart and even restarted my pc but no use.

    Hassan, can I know which packages you installed after a fresh installation of V8?

    Thanks Tarik,

    Umbraco Forms and I did so by mistake and removed it. The other one was the one I mentioned before.

    Hassan, I replicated the issue in my machine and I saw many changes on the source code and to know what was added and what is changed may takes time.

    I suggest that you create other project with a fresh installation and test V8 packages.

    Most of the time, if you install a package they are in the App_Plugins folder. You will need to delete the plugin.

    In the case of the Starter Kits, they usually import Views and scripts, so you can usually delete those too.
    And then there is the 'App_Data > packages > installed' folder where there is an 'installedPackages.config' file where you would delete the entry of the package.

    Like Tarik said, since it seems like you did a new site and not an existing site, it would be best to just create a new project. But just in case you happen to install a package that is not compatible with Umbraco or happens to break the site, the above process should help you recover your site. I have done this.
