    How to prevent the Plugin Manager to try to install the form plugin at startup

    I wanted to have more information on the Umbraco Form Plugin, but ended up launching the install process for the form plugin on our server (Running 7.2.8). It seems like it caused an error and crashed the application.

    Now, the web application can't start since it always tries to install the form plugin at startup.

    Here are the logs that I have:

    So, I guess my question would be : what configuration do I have to change in order to remove Umbraco Form from the list of plugins to install at startup?

    What I've tried so far:

    • Delete the content of the PluginCache folder (but it gets regenerated at startup)
    • Reset the content of installedPackages.config to what it was before the install.
    • Delete the file package.xml inside a subfolder of App_Data

    Alright, seems like I (also) had to delete :

    1 - the following files from the bin folder:

    • Umbraco.Forms.Core.dll
    • Umbraco.Forms.Core.Providers.dll
    • Umbraco.Forms.Web.dll
    • Umbraco.Forms.Web.XmlSerializers.dll
    • Umbraco.Licensing.dll

    2 - The following folder inside App_Plugins:

    • UmbracoForms

    I this might be more than what is needed to stop UmbracoForm to install at startup, but it did the job for me in this case.

    I'd still be happy to have more insights from the community or advice on how to do this better.
