<p>I was using the <a href="https://github.com/doublesecretagency/craft-cpjs" rel="nofollow noreferrer">Control Panel JS plugin</a>, and I entered some erroneous JavaScript that caused it to break the control panel. I then deleted its row in the plug-ins table in the database, and all associated files.</p>

<p>However, when I reinstall it, it finds the old JavaScript and things break again. I cannot figure out where this information is stored.</p>

If you deleted the external JS file, then it shouldn’t be able to trigger anything, correct? Or did you enter the JS directly into the control panel?

I was using the [Control Panel JS plugin](https://github.com/doublesecretagency/craft-cpjs), and I entered some erroneous JavaScript that caused it to break the control panel. I then deleted its row in the plug-ins table in the database, and all associated files.

However, when I reinstall it, it finds the old JavaScript and things break again. I cannot figure out where this information is stored.

If you're using Project Config, you'll want to update the value stored in your config/project.yaml file. Once you've done that, run ./craft project-config/sync to update your database accordingly.
If you're not using Project Config, then you should be able to just update the database directly. Go to the projectconfig table and change this row...
