Whenever we need to update some component info in our registry, or when we need to register a new component, we will have to unlock the components palette changes, before we edit something at the database.
Unlocking the Components palette changes...
Go to the component Palette;
Click at the padlock, located at the upper area of the palette;
A window prompting the User and Password will be shown.
Fill the User field with "admin" (no quotation marks);
Leave the password field empty;
Now that we unlocked the palette, we have total access to make modifications, delete and create components and components folders.
