I'm super new to godot, so I could very well be doing something wrong.
Here's the error that I get when I try to enable the plugin:
Unable to load addon script from path: 'res://addons/DatabaseEditor/DatabaseEditor/plugin.gd'. This might be due to a code error in that script.
Disabling the addon at 'res://addons/DatabaseEditor/DatabaseEditor/plugin.cfg' to prevent further errors.
